Keyboard shortcut for weapons/mining lasers

When I’m mining on my tablet, I can use right thumb to tap a roid and left thumb to fire the laser - on desktop, everything is mouse driven so - over to roid, tap, scroll to laser tap - all on right hand. With thousand of mining cycles anticipated I can see Carpal Tunnel Syndrome down the line :confused:

If there are keyboard shortcuts in PT, I haven’t found where they are.
