📄 Description

This one adds breakpoints - locations in the recording which allow the player to auto-pause when one is encountered.

A breakpoint is new "b" event type in asciicast stream, with optional annotation (comment) as event data.

To add a breakpoint during recording session press a hotkey (specified in config file as add_breakpoint_key).

To add breakpoints to existing recording you add "b" events like this:

...
[1.000000, "o", "some text"]
[2.500000, "b", ""]
[3.750000, "o", "more text"]
[4.500000, "b", "chapter 5"]
...

support for breakpoints in asciicast v2 event stream
setting breakpoint during recording session via hotkey
documentation
~~find good default hotkey, and/or hotkey prefix (like GNU screen, tmux)~~ no default for now
implement pause-on-breakpoint mode for asciinema play command (opt-in with -b/--breakpoints switch)
jump to next breakpoint during asciinema play with hotkey (])
add test
