Using the shift key to enter FX values appears to work differently between local FX and master FX in a track.
For example, if I place the cursor in the master fx column and type Shift+G, then “g” is entered and the cursor moves to the right, so I can enter a value.
However, doing the same thing in the local fx column moves the cursor down, which means if I want to enter a value i need to press Up and right.
Following up on my own post - I did find a bit of a workaround for this: The glide effect works with the shift key when it’s entered into the panning column! The only thing is you can only slide by whole semitones.
Ah, sorry, I need to correct myself above. It’s working on my mac, but not on my linux machine. Looks like an input issue on linux, I’ll do some more digging.
