How do I simulate keypresses?

Hello everybody,

this is my first post here, although I've been using i3 for some months now. I really have to thank the developers for this incredible wm (and for its docs!! :) ).

Some context for my question.
I'm using an Apple keyboard and I set the Meta key as $mod. Since this key is easier to reach than Ctrl, I would like to use it for copy/paste shortcuts and other stuff. E.g., I'd like to press Meta+c to copy the selected text to the clipboard, and Meta+v to paste. I tried different programs (xdotool, xte, xvkbd ...) to simulate keypresses. They do work in a terminal, i.e, if I run in xterm

xte "keydown Control_R" "key c" "keyup Control_R"

I do get ^C as output. However, if I configure i3 like this

bindsym $mod+c exec xte "keydown Control_R" "key c" "keyup Control_R"

nothing happens, probably becasue the command is run in the login shell. So I guess my question becomes: is there a way to tell i3 to send a keypress to the focused container?

Thanks in advance.
Bye

I think you will find your answer in ticket https://github.com/i3/i3/issues/485

A short summary: In the current git "next" version (what will be i3 v4.3 soonish), you can use the following:

bindsym --release $mod+x exec --no-startup-id xdotool key --clearmodifiers ctrl+v

This sounds like a convoluted approach.

I defined some remappings of my keyboard in ~/.Xmodmap. This way, any application that not on a real TTY has CAPSLOCK removed, and functions as an extra ESC there. Might want to make that my i3-modifier, but I am getting addicted to the fast escape key in vim...

Xmodmap is very readable:

$ cat ~/.Xmodmap
remove Lock = Caps_Lock
keysym Caps_Lock = Escape

And it is activated like this in ~/.xinitrc:

xmodmap ~/.Xmodmap

Yes, I thought about remapping the keyboard. The problem is, if I define the **Meta** key to be **Ctrl**, I lose it as $mod. Or, if I then set $mod to be **Ctrl**, I might get some conflicts. That's why I discarded it as an option. I might try it though if I all else fails. Thank you
