Re-bind broken keyboard key to unused key
My aging laptop has a key broken - the D key. To replace the keyboard is too expensive, not worth spending £100 on old hardware. I sometimes use an external USB keyboard just to type D but being laptop is not always convenient.
My question is how to bind key letter D to something else, be it a key combo or one of the unused/unneeded keys?
On this italian laptop keyboard there are some keys i never use like Mac style right click menu button next to AltGr or home/end keys i could spare for this.
