Is it possible for the GM to close the 'Show to Players' windows on the other players screens?

One of my players is severely disabled due to a stroke.  It is hard for him to use a mouse, he has no use of one hand, limited mobility in the other and his eye sight is not great. Roll20 works for most things as we give someone else control over his tokens.  He says where he wants to move, etc.  Other players just do the dice rolls for him. The problem is when we share something from the journal and it opens up on his screen.  We want him to see the material, but we have no way to close the window after he sees it.  So then the process starts of him trying to move the mouse to close the window - which can take a while. I am wondering if there is a macro or something available that allows the GM to close all such windows on players screens.  It's fine if it closes it on everyones screen; it does not need to allow for player specificity. Thanks

No this is not possible through the Roll20 interface.  The best option that I can think of would be a browser scriptlet that could close shared handout popup windows automatically after a set amount of time, or you could add a keyboard shortcut that the player would have to command (such as pressing an F# key), or it could potentially react to a chat message (such as the GM sending a whisper to the player with a specific keyword). 

Hi Andrew R.,  If they hit ESC it will close it.  Alternately, if you assign it to every player except that player and then hit Show it will not show that particular player.  If you would like, feel free to contact me and we can discuss possible solutions for your player.
