How can I emulate a mouse click on a keyboard on linux, e.g. by defining that my right CTRL-key should behave as if I clicked the right mouse button?

There is a "use numeric keypad as mouse" option for both kde and gnome. In kde 4.4 it's located under system settings -> Mouse -> Mouse navigation. I think that it's under accessability settings in gnome. The click actions appears on the keys around the numpad - the "+" key is right click and the "5" key is left click in kde.

If you don't run kde/gnome or want to use a more configurable solution, some sort of combination of these two programs should work:

Use xbindkeys to bind a keypress to

   echo "click 3" | xdo

in order to get a right click.

In KDE 4.7 this has been moved and renamed slightly: Hardware | Input Devices | Mouse | Mouse Navigation | Move pointer with keyboard. Thanks for the tip! Solved my problem perfectly (only have a stylus with no buttons...) – kwutchak Nov 28 '12 at 5:54

In CentOS 6.4 it's here:

System Menu --> Preferences --> Keyboard --> Mouse Clicks (tab) --> Enable the Keyboard to Emulate the Mouse (checkbox)

Now use the keypad '5' to left click (the other keypad numbers move the mouse).

Mouse Preferences (linuxtopia.org)
