Summary: Use basic Emacs keyboard shortcuts (ie navigation) in Gnome-Terminal while using the Bash shell. This post is only interesting for people familiar with Emacs.
This is so simple that I almost afraid to post it…
…One of those things that has been bothering you for years(!), but was never urgent enough to invest time figuring out how to fix…
You're used to Emacs shortcuts. Bash (and many other shells) support Emacs keybindings out of the box. But your default terminal comes with a stupid menu bar. So you press
M-d (Emacs’ “kill-word”; for non-Emacs users: this corresponds to the key sequence
Alt-d) and end up calling the “File” menu entry of the Gnome-Terminal (File is called “Datei” in German, which is my LOCAL). If you your LOCAL settings are English, you will have the same problem with the Emacs shortcut
M-f (in Emacs this is “word-forward”): The Gnome-Terminal will grap the key sequence and open the “File” menu.
Open your Gnome-Terminal
Edit -> Keyboard shortcuts -> DISABLE ALL MENU ACCESS KEYS (If you have German settings the menu entry is called: “Bearbeiten -> Tastenkombinationen -> Alle Menükürzel aktivieren”. Disable the checkbox..)
