tweaks: make three hard-bindings of special keys more efficiently

Browse Source 
Instead of calling a function that tries to find the relevant operation,
just add three hidden hard-bindings at the end of the shortcuts list.

They are hidden because we don't want them to show up in the help text,
because we don't know what to call them (as a Cancel and Suspend key
don't exist on normal keyboards) or naming the key would be confusing
(Sh-Ins is grabbed by the desktop manager and doesn't reach nano).
