Issue description

Various shortcuts used in Godot 3.5 do not work. Overall, the UI does feel a bit inconsistent, but here's a few I'll list:

1. Alt+Left (or Alt+Collapsing) a node doesn't collapse all nodes inside the selected node
2. Alt+Right (or Alt+Expanding) a node doesn't expand all nodes inside the selected node

3. Selections while moving up and down are inconsistent.

4. Pressing Enter on inconsistently selected nodes return an inconsistent rename prompt.

5. Using backspace and hitting enter to return zero values in inspector don't work. Not sure if intentional or not.

6. Hitting tab while going through fields works, but sometimes, fields end up being locked, preventing me from moving to the next field. (I'm spamming tab as soon as I hit the scale Z value):

7. Hitting ESC while having a field selected doesn't stop exiting the field edit.

These are just a few. Let me know if some of these are existing pull requests / issues.

This is already being tracked in #37723.

Alt+Left (or Alt+Collapsing) a node doesn't collapse all nodes inside the selected node
Alt+Right (or Alt+Expanding) a node doesn't expand all nodes inside the selected node

Alt+Collapsing/Expanding was changed to Shift+Collapsing/Expanding. Last PR modifying this part that I recall was #62666; maybe arrow shortcuts were omitted.

Selections while moving up and down are inconsistent.

I don't see any different from 3.5 behavior.

Pressing Enter on inconsistently selected nodes return an inconsistent rename prompt.

Can't reproduce.

Using backspace and hitting enter to return zero values in inspector don't work. Not sure if intentional or not.

Same as 3.5.

Hitting ESC while having a field selected doesn't stop exiting the field edit.

Might've been caused by #67397
