📄 Description

This one adds recording pausing/resuming functionality, that can be used to temporarily turn off capturing of stdout/stdin by pressing a hotkey. This is useful when you want to execute commands during the recording session that should not be captured (e.g. pasting secrets).

Similarly to #341, the hotkey for toggling pause is hard-coded at the moment to ctrl+p ("p" for "pause capture"), but it is very likely to conflict with many interactive applications (e.g. vim), so we may want to find a better one, or go with a prefix + key (like ctrl+a <key> in screen, ctrl+b <key> in tmux).

It may be a good idea to show a notification that pause/resume actually happened after pressing a hotkey. Printing something to the terminal is not a good idea here, since it would potentially overwrite whatever was printed before (in fullscreen apps like vim), so I believe an external tool is the best choice. We could have a setting in a config file notification_command which would be invoked to notify about pause/resume (also about setting breakpoint in #341). You could then set it to show the notification in tmux's status bar (via tmux display-message) or show a desktop notification (notify-send, Growl, etc) or play a sound.

toggle pause during recording session via hotkey
stop time when paused
documentation
notifications
find good default hotkey, and/or hotkey prefix (like GNU screen, tmux)
