This should be an easy fix.

The 'R' key is used as a hotkey in 3 places on the capship interface. Depending on what part of the UI has focus, it'll switch to Turrets or repair your ship.

See screenshot:

They aren't over-loaded, they are just multi-threaded.

Bibbity bobbity bump.

This was an easy fix for the livery button, why not here?

Change "Turrets" to "Turrets" and make it so after "Repair/Refill" is selected, the pane on the left gains focus.

The "u" key is set to bring up the sector list. but "e" is available for that.
And I'll do "p" for the "Repair Ship" button on the left.

Changing focus like you suggest is not that simple.

Umm, 'e' is most certainly not available. It's already in use here for "Refill all ammo"

Please leave the two for repair and refill what they are. Pressing "e" and "r" to do this right now is very convenient if you're using the default keyboard controls. Change the ones on the right instead if you can...

The whole reason I'm reporting this as a bug is because the crap on the right interferes with that.
