pause program until a specific key is pressed, while in background.

Hi everyone, i have this matlab code sending info to another app. While working , i've full screen on this secondary app, and matlab is on background.

Matlab will run some code up to a point, then it needs to be stopped,i need to press a specific button (for example right mouse click) to allow Matlab resume its operation.

I've tried differents pause/wait methods, but they all require a focus on Matlab or on a figure. The problem is to get the thing to work while matlab is on background.

Thank you for your attention.

This might be possible with some listener if that secondary app can change something that Matlab can watch, like a file. You might also be able to hack something together with autohotkey.

The secondary app only receives data from Matlab, but could not send data to Matlab. Also the app does not save files while working.

You might still be able to get Matlab to detect something that autohotkey can do
