Why am I unable to get my nook to remap the upper left button to work as a CTRL key?

Question

Recently, I had to re-root my nook simple touch after the stock recovery removed the su binary. Unfortunately, it deleted my settings for remapping my upper left page button to use as a CTRL key. I would love to go back to using the terminal app running an Ubuntu Distro.

I tried fixing the problem by installing the patched jars needed for nook touch tools. Although, I successfully installed them but when I go to the app to do the remapping the CTRL option no longer exists in the list of options!

I already found my keymap file in this directory

/system/usr/keylayout/

The file is named TWL4030_Keypad.kl

The content of the TWL4030_Keypad.kl file is here.

Answer 1

I furnished two solutions to my problem.

Get into the nook touch tools app and set up key bindings by clicking the button on the far right. You should see something like this. Where it says, left-bottom button select the option Volume_Down.

After rebooting get into the terminal app's settings to set up key bindings.

The terminal app has options that permit you set up key bindings that will allow me to emulate the control key.

I have taken screenshots of the terminal's settings. I go into nook touch tools and set up the binding to use the left bottom page button to be used as a volume button. You must do this for it to work. Select preferences.

The next step is to go to keyboard and you'll see the select control key option. Under the sub-list of options select volume-down for use as the CTRL key. Then you can now use the left bottom page button as the control key.

The second option is to download the hacker's keyboard and install the multi-touch zips with the CWM based recovery on a sdcard via re-boot. But the ctrl key doesn't work so you still have to set up the settings in the terminal app. The multi-touch hack allows you to use two keys at the same time therefore allowing the binding of the alt key to be used as the ctrl key.
