commit a1aa453e99f198186d39b90b1229cc1bcb8dc466
Author: Markus Teich <markus.teich_AT_stusta.mhn.de>

    select or open new tab with Ctrl-T
    
    The default config will display all open tabs in dmenu. You can either select
    one of them, or if you enter a string, that does not start with „0x“, tabbed
    will open a new tab and run the command specified at tabbed-startup but append
    the entered string to the command first.
    
    With
    tabbed -r 2 surf -e ''
    you can hit Ctrl-T and either select an already opened tab or enter an URL,
    which will be opened in a new tab with surf.
