Let's assume I have added the following keyboard map in /usr/share/X11/xkb/us
. Why can't use the the keyboard key as a Pointer Button.
partial alphanumeric_keys
xkb_symbols "alt-intl" {
name[Group1]= "English (US, alternative international)";
include "us"
key <AB04> { [ Pointer_Button1 ]};
};
Under the settings option you need to enable the Mouse Keys under
All Settings->Universal Access->Pointing And Clicking
The setting is also described at the following question.
