Apparently this code in ttyplay is firing:
case '0':
speed = 0.0;
break;But, I am *not* pressing 0 on the keyboard! The full text that ttyplay reads from stdin looks like this: ^[[>1;2801;0c So vim originally sends a terminal escape sequence that causes the terminal to respond with this, and the playback causes this to reoccur, and be misinterpreted as a user pause request. I have not tried to look up what the terminal response code here is used for, but there seem to be several standard ones. http://www.termsys.demon.co.uk/vtansi.htm One approach to fix this would be to ignore incoming terminal escape sequences that come immediately after '\e'. An alternate approach would be to try to filter out the recorded escape sequences that would result in such responses. Another option would be to stop treating 0 and 1 on stdin as pause/unpause, and instead perhaps let the user press the space bar to toggle playback. I've attached a patch that does that. BTW, I can reproduce the problem with recordings taken in xterm and sakura (a VTE based emulator), but not at the linux console. -- see shy jo
