Using Photoshop shortcuts in Premiere pro

One of the most annoying things in Premiere pro is when I need to resize a lot of videos to zoom and crop --

it keeps selecting different tracks or I can't seem to select and click and drag properly. 

When I use the mouse scroll to zoom out, I have to use the hand tool to place the frame in the centre and click out again - I wish you could just hold a button to do that (like in Photoshop you hold the space bar and it sets it to the hand tool temporarily)

The snap feature was also better when you could do it just by holding the shift button, I don't understand why it's gone :((( it's so annoying to hit S on and off repeatedly. I wish you could assign more functions to keys manually if you don't set it as default.

Another thing that would be appreciated it being able to have two program source monitors- I have multiple monitors and would like to be able to have several program source monitors so I can see one small one on the main editing screen and a big one on the reviewing screen.

Or at least have one button so I can assign ONE BUTTON to set my playback screen to a certain monitor because it's annoying having to go in and set the settings each time because I can only assign the playback settings to a key.
