I love pianobar. However, until yesterday I hated pausing and moving to the next video using pianobar. I had a small terminal dedicated for pianobar and every time I had to change the song or pause, I used to select the window and then hit the right shortcut. I love hotkeys, the allow you to control your stuff without opening windows. I also happen to use tmux a lot. And it hit me yesterday, I could have easily bound hotkeys to send the right key sequences to pianobar running a tmux session. Here is how I did it.
I use xmonad, so I wired up
Windows + Shift + p to
tmux send-keys -t scratch:1.0 p &> /tmp/null.log
So, now whenever I hit the right hotkey it types the letter ‘p’ in the tmux session
scratch window 1 and pane 0, where I have pianobar running.
I use xmonad, but you should be able to put these in a wrapper script and wire them up with any window manager or with unity.
