Using other keys for the waitKey() function of opencv

Question

I\'m working on a program (python ,opencv) in which I use the spacebar to go to the next frame, and Esc to exit the program. These are the only two

Answer 1

If you want to pause the program to take screenshots of the progress

(shown in let's say cv2.imshow)

cv2.waitKey(0) would continue after pressing "Scr" button (or its combination), but you can try this

cv2.waitKey(0)
input('')

cv2.waitkey(0) to give the program enough time to process everything you want to see in the imshow and input('')

to make it wait for you to press Enter in the console window

this works on python 3
