title: Howto go to beginning of line in tmux after remapping prefix to CTRL+A?
body: <p>following the suggestion in this Archlinux wiki, in the <a href="https://wiki.archlinux.org/index.php/Tmux" rel="noreferrer">page about tmux</a> I remapped the command key prefix to <code>C-a</code>, to mimic GNU screen and to have something easier on the keyboard than <code>C-b</code>. So my .tmux.conf became this:</p>
  
  <pre><code>set -g default-terminal "screen-256color"
  unbind C-b
  set -g prefix C-a
  set-window-option -g mode-keys vi
  bind h select-pane -L
  bind j select-pane -D
  bind k select-pane -U
  bind l select-pane -R
  </code></pre>
  
  <p>However, while in screen it was possible to use <code>C-a a</code> to jump to the beginning of line, this does not work any more in tmux. As a sidenote, I'm using iTerm2 without the tmux integration.</p>
  
  <p>Does anybody know how to solve this?</p>
  
  <p>Thanks!</p>
