meow mode has beacon mode for creating multiple cursors. Multiple cursors are called beacons. If there are beacons, any macro you execute will be applied to all beacons. This is multi-cursor editing.
Beacon mode just lets you create multiple beacons.
meow mode tries to not interfere with emacs keys, so you can use emacs keys. meow mode has keypad mode which makes it easy to press prefix keys such as Ctrl-c and Ctrl-x.
A few problems with meow mode
- key bindings are not defined, so you have to copy key bindings from meow mode documentation
- beacon mode is not documented well at this moment, but this documentation issue will be fixed in the near future.
