I am trying to send keystrokes via xdotool.  However, sending does not work properly.Below is the log of a script that should select all the text in Gedit and copy it (but it does nothing instead), along with its output (captured by redirecting both stdout and stderr):+ xdotool getwindowname 29360262*Unsaved Document 1 - gedit+ xdotool key --window 29360262 ctrl+a+ sleep 1+ xdotool key --window 29360262 ctrl+c+ sleep 1I have tried with Thunderbird, and the script does send the keys, but without modifiers (no Control, that is).  By the way, in the script, keys are surrounded by , like ctrl+a.The difference between Gedit and Thunderbird may be that Gedit is a GTK3 application, whilst Thunderbird seems a GTK2 application (but Firefox, which seems a GTK3 application, behaves like Thunderbird).xdotool version 3.20141006.1Operating System: Debian GNU/Linux 8.1 (Linux kernel 3.16.0-4-amd64)Desktop Manager: GNOME Shell 3.14.4  
`xdotool` does not send keys
