System Settings Bluetooth sans mouse

[Henry Pfeil]

I have a bluetooth mouse. There is no way to re-connect it without using a pointer. I also have a Wacom tablet that I 
use via USB, since bluetooth typically disconnects. I have to use that in order to re-connect my bluetooth mouse. There 
is a ham radio station nearby which may interfere with bluetooth, or neighbors. A keyboard shortcut to connect would be 
nice. I have to use the tablet pointer to delete the old mouse connection, then search for the current channel that the 
mouse is using before connecting it. There are no keyboard shortcuts to do any of that.
Question: How do you connect a bluetooth mouse using only a keyboard?  /usr/bin/bluetoothctl, since KDE cannot do that.
