I have not encountered this problem in practice. The Alt method may not work if an application interprets Alt+Number as a distinct key combination from F-Number. Launch a Terminal Window From the Dash You’ll find the Terminal application included with your other installed applications. A graphical GNOME Terminal window will pop right up. Byobu passes the key combination through, htop interprets it as F4, and enables filtering. To quickly open a Terminal window at any time, press Ctrl+Alt+T. Gnome Terminal passes the inputs separately, mc interprets them as F10, and mc exits.Įxample with Alt: I want to press F4 to filter htop, but byobu intercepts F4 and interprets it as 'next window'. They are also useful with a physical keyboard when your terminal program or another program running in the same session (eg byobu/screen/tmux) intercepts F-keys for its own purposes.Įxample with Esc: I want to press F10 to quit mc, the Midnight Commander, but Gnome Terminal intercepts F10 and interprets it as its menu key. These shortcuts are very helpful when using a terminal emulator on a phone or other restricted device that lacks physical F-keys. You can often use Esc followed by Number, or Alt+Number to simulate F1- F10, using 0 for F10.

However, if for whatever reason you can't install a new keyboard, there are other alternatives, as long as your terminal app allows you to press Esc and/or Alt. Also, note that you may have a time limit: some applications only recognize escape sequences if they come in fast enough, so that they can give a meaning to the Esc key alone.Īs Drake Clarris suggests, on Android, you can install alternate keyboards, such as Hacker's Keyboard that include F-keys. Since the sequences may be awkward to type, do investigate changing the key bindings in your application or using another terminal emulator. Ctrl+ V inserts the next character (which will be the escape character) literally, and you'll be able to see the rest of the sequence, which consists of ordinary characters. $ for x in do echo -n 'F$x ' tput kf$x | cat -A echo doneĪnother way to see the escape sequence for a function key is to press Ctrl+ V in a terminal application that doesn't rebind the Ctrl+ V key (such as the shell). For example, the shell snippet below shows the escape sequences corresponding to each function key. I have some unsaved work and I don't want to lose them. These sequences are stored in the terminfo database. 54 I'm unable to return to the GUI with Ctrl + Alt + F7 (or any of the 12 function keys). You can use the tput command to see what escape sequence applications expect for each function key on your terminal. Apart from a few common ones that have an associated control character ( Tab is Ctrl+I, Enter is Ctrl+M, Esc is Ctrl+[), function keys send escape sequences, beginning with Ctrl+[ [ or Ctrl+[ O.

So al function keys are encoded as sequences of characters, using control characters. Terminals only understand characters, not keys.
