Summary
hi,
it looks like the only way to commit a selected option in quickphrase is by pressing Spacebar. Pressing Return/Enter exits the quickphrase input method. I have unsuccessfully tried to adapt myself but months later I still find myself pressing Enter when I meant to commit.
Using Enter/Return to commit works fine in Unicode input mode.
request: setting Enter/Return as a commit key along with Spacebar, or an option to use the Enter key to commit a suggestion from quickphrase.
