What is the command executing when you press this shortcut? Usually you need to use an option with the terminal to execute a command. Most terminals use the option -e COMMAND , but it can be different for a few terminal apps. In example my terminal is “Konsole” and to open a new terminal with “Vim”, I need to use this command: konsole -e nvim . Or when I want to use arguments for vim itself, I can do it like this konsole -e “vim -R $HOME/Downloads/test.txt” as an example.
So find out how to do this with your terminal and use that as a command for your ctrl-e shortcut.
