I have custom keyboard shortcuts enabled under Gmail's settings. Today I was fiddling around with them, and now I cannot open a message using the Enter key. I can still do it with my custom keyboard shortcut for that, o. Using
ENT as a value does not work, and even setting
ENTER as the value by bypassing the character limit does not work either.
How do I re-enable usage of Enter to open a message from the threadlist?
