After using the Ctrl + "arrow keys" for 13 years to switch virtual desktops in X windows, I've been convinced recently to change to using the Super keys instead (the windows key and the context menu key, which I've remapped). This all works fine for the most part. However, something is still picking up the key events that these keys are sending as if they are a normal alphanumeric like key.
For example, I first noticed this in Google Docs spreadsheet that if I press the windows key alone over top of a cell, that it starts editing that cell. It doesn't insert anything, it just sends a key event that Firefox sees and starts editing the cell. This caused problems on a collaborative document I was working on as the way Google docs works, it led to me accidentally erasing the data in a few fields before I realised what was going on.
I like using the super keys, but I want them to behave more like a Ctrl or Alt key does in that its a modifier key and doesn't send anything until a second key is pressed.
My setup is the following:
- Ubuntu 10.10
- XFCE 4
- Microsoft Natural Ergo 4000 keyboard (with the logo scratched out of course)
- The following is my .Xmodmap file:
remove Lock = Caps_Lock
keycode 66 = Escape
! The below maps my other windows context menu key.
keycode 135 = Super_R
Edit: As requested, here is the relevant output from xev for a keypress and keyrelease of my Super_L (left windows key)
