I looked all over and couldnt find solution. I like to use wireless keyboard with my cnc and I cant figure out how to bind a key or make a shortcut, hotkey or shortkey to zero the axis. Can anyone please help? Thanks

Look under "Sytem Hotkeys" in the "config" drop down. If that doesnt work for your pendant (it will work for your keyboard for sure). It will be under the "configure plug ins"section.

To make a shortcut key to a screen button you need to use a screen designer to set up that key. Word of warning, a lot of keys are already used as standard so make sure you do not duplicate or you may get unexpected results.
Another thing to be wary of is a wireless keyboard may not be a good idea as if the keyboard loses communication there may be unpredictable results.
Personally I dislike using keyboard shortcuts but thats just me
