Is there any way to use "hot corners" to execute a command?

I'd like to be able to trigger an action (exec) by moving the mouse to a corner. I think this would be handy, for example, to trigger skippy-xd for functionality similar to gnome-shell.

Is this possible in i3?

No, i3 does not offer anything like that. However, you can use xdotool to do that. Check out man xdotool for behave_screen_edge. Excerpt:

        # Activate google-chrome when you move the mouse to the bottom-left corner:
        xdotool behave_screen_edge bottom-left \
          search --class google-chrome windowactivate

        # Go to the next workspace (right). Known to work in GNOME (metacity and compiz)
        xdotool behave_screen_edge --delay 500 bottom-right key XF86Forward

        # Activate firefox and do a web search in a new tab for text in your clipboard
        xdotool behave_screen_edge --delay 1000 top-left \
            search --classname Navigator \
            windowactivate --sync key --delay 250 ctrl+t ctrl+k ctrl+v Return

Note that this only works on the corners of the root window, so if you use multiple outputs, it may not be quite as useful depending on your setup.

That works well on my laptop's display. Unfortunately, I'm using external monitors about 90% of the time, and I cannot get xdotool to do anything with 'behave_screen_edge' on those monitors. Thanks for the tip though; xdotool looks like a very useful tool for i3 users.

I wrote a tool called xedgewarp which could do this even with external monitors. It would have to be implemented, though.

@Airblader Sounds interesting. Do you have it on github or anything?

Yep :) I already opened this as an issue as well.
