If -e is specified, then the string is interpreted as an Emacs-style keystroke sequence. The following characters and modifiers are accepted: 'C' (Ctrl), 'A' (Alt), 'Del', 'Up', 'Down', 'Left', 'Right', 'Esc', 'F1' to 'F12', 'Win', 'Enter' as well as the same characters that are accepted without the -e flag. Key strokes are combined using the '-' character. For example, "C-a" will input Ctrl and 'a' pressed together. "C-A-Del" will produce the famous Ctrl-Alt-Del sequence.
