The general format is _action=combo1...comboN_. That is, each action
may have one or more key combinations, space separated. Each
combination is on the form _mod1+mod2+BTN\_<name>_. The names of the
modifiers and the key *must* be valid XKB key names. You can find the
button names using *libinput debug-events*.
combination is on the form _mod1+mod2+BTN\_<name>_[-COUNT]. The names
of the modifiers and the key *must* be valid XKB key names. You can
find the button names using *libinput debug-events*.
The trailing *COUNT* is optional and specifies the click count
required to trigger the binding. The default is *COUNT* is omitted is
_1_.
Example: *primary-paste=Control+BTN_LEFT-2*
Trigger _primary-paste_ when *ctrl* is pressed, and the left mouse
button is double clicked.
A button can only be mapped to *one* action. Lets say you want to bind
*BTN\_MIDDLE* to *fullscreen*. Since *BTN\_MIDDLE* is the default
