If you want to just disable that one shortcut, then simply execute these 2 lines:
mkdir -p ~/.config/xfce4/terminal
echo ‘(gtk_accel_path “<Actions>/terminal-window/contents” “”)’ >> ~/.config/xfce4/terminal/accels.scm
Close all instances of xfce4-terminal to apply the change.
xfce4-terminal opens its help when pressing F1. The process to change that is *censored* – see here:
What this means is:
Open Settings/Appearance, then goto tab “Settings” and check “Enable editable accelerators”.
Then in xfce4-terminal, click “Help” and hover over “Contents F1”. Press backspace or delete.
For safety, disable the “Editable accelerators” again.
This creates the file ~/.config/xfce4/terminal/accels.scm, which seems to contain all keyboard shortcuts.
But having just the shortcuts that you want to change in there seems to work as well.
Thanks! It works! But try to copy and execute bash commands from this article – they are broken by wordpress quotes substitution
