Syntax
Usage
The setkey command lets you define a list of words that should be stuffed back onto the command-line whenever you press a particular function key. The syntax is exactly the same as used in the set, setenv and alias commands, where fkey is any of the function keys F1 through F12, case-insensitive.
setkey with no operands reports the current function key bindings, if any. setkey pattern lists the bindings for any keys whose names match the pattern. The corresponding unsetkey command discards key bindings. The fkeylist can be typed with either spaces or commas between the names of the keys.
Using the function keys
Fn
Clear the command line, post the text bound to this key and execute the command.
Alt-Fn
Insert the text bound to this key at the cursor location but don't execute it yet.
Ctrl-Fn
Clear the command line and post the text bound to this key but don't execute it yet.
Since the function key's bound text is written back into the command line inside command line editor, the substitution happens ahead of any parsing of the command line into words or expansion of ! or % history references so it is possible to meaningfully embed these kinds of references into the key binding.
F1 to open the user guide
The default startup.csh uses setkey to cause F1 to open the user guide.
# Set f1 to open the user guide. setkey f1 open ^$shell:h:h\UserGuide\index.htm |
$shell refers to the path to the currently running csh.exe; escaping the $ with ^ defers evaluation to run-time, simply to avoid dealing with a path that contains spaces. The :h operator returns the directory containing.
