Slaving player view to GM's view?

I have been using Roll20 in my face to face game. I run a second browser tab on my laptop opened on a second monitor (a big tv). The second browser is logged in as a player account. The problem is that when I want to change the view on the players tab I have to get the mouse on the second monitor and adjust it there. I wear closeup glasses to read my notes so the monitor is somewhat blurry and hard to adjust with changing glasses. Is there a way to "lock" the players map view to the GM's view? In terms of positioning and zoom, I don't want the player screen showing the secret GM stuff. 

I'm not sure about locking, but have you been using the shift + hold left mouse button?  On the DM view that will "ping" the map and force all views to center on that spot.

Shift-Hold-Click is the only real option here without some sort of external programming solution that would require all players to install and run software, and would doubtless bring complications of its own. It will center the player view on the click, but it will not change zoom level or track the gm view in real time.

I was not aware of the Shift-Hold-Click, I will try it next time. In my case I don't have any actual players running roll20 it's two browser windows on my laptop so running software wouldn't be a problem. If the actual players were running roll20 then it wouldn't be a problem and they could adjust the screen themselves.

Here's the relevant bit of the wiki.
