I was previously using Ubuntu 14.04 and accelerators (keyboard shortcuts for activating menu items) worked just fine. For example, in gnome-terminal, I could hit Alt-E to open the Edit menu, then P to select/execute the Paste menu item.
Since upgrading to 16.04 (did a fresh install, to be precise), this only works in some apps, like LibreOffice, but no longer works in GNOME Terminal.
According to https://help.ubuntu.com/stable/ubuntu-help/keyboard-nav.html, this should still be possible:
Hold down the Alt key to reveal accelerators: underlined letters on menu items, buttons, and other controls. Press Alt plus the underlined letter to activate a control, just as if you had clicked on it.
but this is the behavior I observe instead:
I can hold to get the menu to appear, but:
- No letters are underlined to indicate accelerators
- Pressing the accelerator key that I know exists doesn't open the menu
Instead, when I press Alt-E, it simply prints ^[e
in the terminal.
This is highly annoying since I used to use those keyboard shortcuts as the main way to access the menus.
