copied!<p>Took me some time, but finally managed to get what you want (and eventually, what I also want :) with <code>xdotool</code> (on Ubuntu <code>sudo apt-get install xdotool</code>).</p> <p>With this script, you can have any application behave like you asked:</p> <pre><code>#!/bin/bash SEARCHED_WINDOW=$1 COMMAND=${2:-$SEARCHED_WINDOW} SEARCHED_WINDOW_CLASSNAME=toggleApp$SEARCHED_WINDOW WINDOW_ID=$(xdotool search --classname $SEARCHED_WINDOW_CLASSNAME) VISIBLE_WINDOW_ID=$(xdotool search --onlyvisible --classname $SEARCHED_WINDOW_CLASSNAME 2>/dev/null) if [ -z "$WINDOW_ID" ]; then $COMMAND 2>/dev/null & pid=$!

In KDE : <em>System settings</em> > <em>Shortcuts and gestures</em> > <em>Custom shortcuts</em>. Then <em>Edit</em> > <em>New</em> > <em>Global shortcut</em> > <em>Command</em>.</p> <p>Plus, this script works with any app, should work with any <a href="http://en.wikipedia.org/wiki/Extended_Window_Manager_Hints" rel="nofollow" title="EWMH">EWMH</a> compliant window manager, and allows you to have other instances of the same app (this is why I added the class trick).</p>
