I found these tips in the axim site. They might be useful to some here. I simply cut and paste what I found. Credit should go to the munk@aximsite. The changes are through editing the .ini files directly and not through the built-in "settings" option.

PLEASE NOTE: Making changes to the settings do not seem to be case sensitive but just to be cautious, try to keep everything similar in fashion such as capitalizing the first letter of a parameter. Also note that I tested all of these settings but there could easily be issues or variances from WM2003se version to WM5.

Page UP/Down/Left/Right a full screen at a time
By default Opera moves to the next object on the web page as you press the up, down, left, right buttons. This modification will scroll an entire page as you press each button.
1) Edit the "input.ini" file located in "\Application Data\Opera"
2) Go to the "[Browser Widget]" group
3) Change "Down = Navigate down" to "Down = Page down"
4) Change "UP = Navigate up" to "UP = Page up"
5) Change "Left = Navigate left" to "Down = Page left"
6) Change "Right = Navigate right" to "UP = Page right"


Turn off the scroll bars
This turns off the up/down scroll bars and gets some screen space back for viewing. This works great in conjunction with the modification listed above.
1) Edit the "opera.ini" file located in "\Application Data\Opera"
2) Go to the "[User Prefs]" group
3) Change "Show Scrollbars=1" to "Show Scrollbars=0"


Cycling between multiple Opera Windows
This already exists with your default configuration. Simply bring up the soft-keyboard and press "8".
To change the default key that switches between windows do the following:
1) Edit the "input.ini" file located in "\Application Data\Opera"
2) Go to the "[WinCE Application]" group
3) Change "8 = Cycle to next window" to whatever number or letter that you would prefer.

NOTE: You can use words like "Tab", "Enter" or "Space" to indicate that specific key. I like using the big buttons like "Space" to toggle between screens. These buttons can be done with many of the other options on this page.

ALSO NOTE: The page needs to have focus for this option to work. If you have a text box selected when typing these letters/buttons, it will simply enter into the text field and not be seen as a special command. In other words, if it doesn't work, tap on a blank part of the web page and then try it again.


Open a new URL quickly
This already exists with your default configuration. Simply bring up the soft-keyboard and type "1".
To change the default key do the following:
1) Edit the "input.ini" file located in "\Application Data\Opera"
2) Go to the "[WinCE Application]" group
3) Change "8 = Cycle to next window" to whatever number or letter that you would prefer


Open a "Window List" of open browser windows
This already exists with your default configuration. Simply bring up the soft-keyboard and type "9".
To change the default key do the following:
1) Edit the "input.ini" file located in "\Application Data\Opera"
2) Go to the "[WinCE Application]" group
3) Change "9 = Show window list" to whatever number or letter that you would prefer


Show Opera's Help file
This already exists with your default configuration. Simply bring up the soft-keyboard and type "0".
To change the default key do the following:
1) Edit the "input.ini" file located in "\Application Data\Opera"
2) Go to the "[WinCE Application]" group
3) Change "0 = Show Help" to whatever number or letter that you would prefer


Toggle FullScreen Mode
This is setup for phone based users. By pressing the "*" on the phone pad you will toggle between full-screen and normal display.
To change the default key do the following:
1) Edit the "input.ini" file located in "\Application Data\Opera"
2) Go to the "[WinCE Application]" group
3) Change "F8 = Enter fullscreen | Leave fullscreen" to whatever number or letter that you would prefer


Toggle Fit-to-Screen (Mediumscreen) Mode
This is setup for phone based users. By pressing the "#" on the phone pad you will toggle between fit-to-screen and normal layout.
To change the default key do the following:
1) Edit the "input.ini" file located in "\Application Data\Opera"
2) Go to the "[WinCE Application]" group
3) Change "F9 = Enable mediumscreen mode | Disable" to whatever number or letter that you would prefer

COOL TRICK: With this option you can specify the middle button of your controller to toggle between the two modes. Simply change the option to "Enter = ...". Unfortunately, I really wanted this to work for "Full Screen" toggle option as it will switch to full screen mode but will not switch back. What's with that?


Change the amount of data cached on your PDA
By increasing the "cache" size your browser keeps more copies of images, web pages and such that you have viewed. The next time the same image or web page is browsed, Opera does not have to download an it and simply loads it straight from your PDA. So, larger is faster.
1) Edit the "Opera.ini" file located in "\Application Data\Opera"
2) Go to the "[Disk Cache]" group
3) Change "Size=2000" to whatever value that you would prefer
NOTE: Keep in mind that this is how much storage space is being used on your PDA so, don't set it too high. Probably 8000 should be the maximum value.


Move data and cache around to save memory
By default Opera installed a bunch of files and keeps cache in precious application data space (RAM). At least with the WM2003se version. By moving all of these files to a CF Card or SD memory stick you free up valuable RAM.
1) Edit the "Opera.ini" file located in "\Application Data\Opera"
2) Go to the "[User Prefs]" group
3) Change "Opera Directory=\Application Data\Opera" to a location that you would prefer such as "\cf card\opera"
4) Change "Help Directory=\Application Data\Opera\Help" to a location that you would prefer such as "\cf card\opera\help"
5) Move the following files and folders to the location that you specified above:

cach4 (folder)
help (folder)
imgcss (folder)
startpage (folder)
styles (folder)

chartables.bin
cookies4.that
global.that
opcacrt6.that
opera.dir
oprand.that
opssl6.that
viger.that
vlink4.that

You are left with these files/folders in "\Application Data\Opera"
skin (folder)
opera6.adr
input.ini
opera.ini
english.lng


Change the drop-down url history length
By default Opera remembers the last 10 websites that you visited in its drop-down navigation bar. You can up that amount by doing the following:
1) Edit the "Opera.ini" file located in "\Application Data\Opera"
2) Go to the "[User Prefs]" group
3) Change "Max Direct History Lines=10" to a number that you would prefer such as "20"


Change the default download path
By default Opera will download all files to "My Documents". To change this do the following:
1) Edit the "Opera.ini" file located in "\Application Data\Opera"
2) Go to the "[User Prefs]" group
3) Change "Download Directory=\My Documents" to whatever location you would prefer


More in fact, could be done to the .ini file to configure Opera. Try them. But always backup first, just in case things mess up.

Have fun and enjoy.

Yo, brother. looks very complicated leh. On WM5 it does not affect free program ram Upgrade to WM5...solve the hussle.

It is less complicated then it seems. You don't have to apply everything. For example, if you just want to move Opera to your SD card, simply make those changes under the specific paragraph.


Wait till I got nothing to play with WM2005SE. But the days are not far. Or maybe change my PPC to one that comes with WM5. At the moment, broke.

Has anybody tested these tweaks on WM5? Do you guys think it is worth the effort to develop a small application to make it much easier to apply these tweaks? If they have been tested to work on WM5 and there's a demand for such an application, it'll be in my future project list.

it is surely great to have an small application to do automated changes (with a click) to the registry or ini files.

to make such a effort worth while, this small application such be generic, however it such be 'programmable' to work with future/application. But this will mean we need to 'config' the application....

hah? config a small application to config other application... ?!?!?
sigh... no good solution.

All the above tweaks work on WM5 (hp rw6828) and WM6 (Dopod 838 pro ).

Nice indeed. Now the valuable rom are more free!

Cheers!

I just learnt the correct way of moving the cache directory

Instead of modifying this line:
