Ok. I have a Thinkpad laptop and my bottom left key is a function key instead of a Control key like I'm used to.
So I fired up
xev, pressed the Fn and got a keycode of
151. So I cleared all of it's current settings and ran the command :
keymap -e "keycode 151 = Control_L"
It runs successfully. So then I save this to my file
~/.Xmodmap. Then I log in and out of my account.
Yet when I open firefox if I attempt to use Fn + T to create a new tab the Fn key is not recognized as control and nothing happens.
What am I doing wrong?
