From the README:
Mark-ring Atom package
Easily create multiple cursors without your mouse.
This package allows you to create multiple cursors in places other than simply above and below the current cursors. All you need to remember is one easy-to-use shortcut that does everything!
- Mark your cursor location with a keyboard shortcut
- Use the mouse or keyboard to place another cursor
- No need to worry about moving cursors by accident
- Platform independent keyboard shortcuts
apm install mark-ring
Or install through the Atom setting menu.
You only need
mark-ring:mark-or-recall to use this package. It will mark under your cursor, but if there is a mark already there, it wil clear and recall all marks.
