Mobile Development: Hooking the keyboard – KeyToggle

KeyToggle

Extend your keyboard to get function keys by pressing numbers.

With keytoggle you can define a ‘sticky’ key that will change the beahviour of the number keys. As long as the sticky key is ‘active’, number keys from 1 to 0 will produce the function keys F1 to F10. If sticky key is active, the left LED will light in green.

To start keytoggle just tap it or let it start by a link in StartUp. If keytoggle is loaded, you can see a small yellow arrow sign in the taskbar.

If you tap this symbol, you are asked, if you want to unload the app. If the registry does not have values defined for keytoggle, it will use default values. If you try to launch keytoggle a second time you will get a message box. Only one instance of keytoggle can run at a time.

Using the registry you can define the behaviour of the sticky key. In example, you can have the sticky key remain active until it is pressed again, let it ‘go off’ or ‘fallback’ after a period of time or let it fallback after a number key has been pressed. If the sticky key is pressed again, it will always fallback.

Ubuntu testing maverick netbook daily builds

Privately I am running an Acer Aspire One D150 (AAO). Although it has Windows XP installed, I did not hesitate to break the partitions and installed first Ubuntu Netbook edition (8.04) and actually updated up to 9.04.

I am always impressed about the great tools available freely for all kinds of usage.

Now Maverick (10.10) Netbook edition will come and I like to test it from time to time but without burning CDs, creating bootable USB sticks. So I stumbled about testdrive. Although this a great tool, it was not able to run the daily build iso inside virtualbox on the AAO.

I remembered that grub should be able to mount iso and start the AAO from that iso. Now I able to test maverick daily builds without touching my well running ubuntu. I can do updates to the iso using zsync and can start, run and test maverick with acceptable performance.
