playback hotkeys and metronome

Hi all,
recently I've had to play with other DAWs (Mostly Logic X and GarageBand) and I've been increasingly frustrated about the lack of tap tempo and live slider to adjust it. 
Another thing I can't seem to find, I use now a wireless keyboard and I would like to move the time cursor backward/forward, can't seem to find the hotkey to do that, is that possible?
 
Thanks for listening,
Cedric

Thanks a tad,
I'll try the script way, I already use W for RTZ but what I need is exactly what you have in those CALs.
 
Cheers mate!

found it in the regular commands for views, bound to AltGr left/right for zoom in/out, and Ctrl left/right to move, it's really fast.
