Bubbl.us mind map editor has many keyboard shortcuts, designed to reduce user's reliance on the mouse while brainstorming. Use of the following shortcuts depends on the current context, i.e. whether you're editing text in a bubble, or a line at the moment.
Press ⌘Ctrl + Z to undo your last action.
Press ⌘Ctrl + Y, or ⌘Ctrl + Shift + Z to redo.

If you release the Shift key while dragging, but before releasing the mouse button, then the bubbles inside the selection will replace selection instead of adding to it.

Note that Bubbl.us clipboard is separate from your computer's clipboard; you can still copy and paste text from and to bubbles when editing them. Also, Bubbl.us clipboard is saved and restored when you sign out / sign into Bubbl.us.
Press ⌘Ctrl + Enter to create a new child bubble.
Press Tab to move editing focus to the next sibling of the currently edited bubble. If the bubble has no siblings after it, a new bubble will be created under the same parent. If you're editing a top level bubble, another top level bubble will be added instead.
Press Shift + Tab to move editing focus from the current bubble to its previous sibling. If there are no previous siblings, the focus will move to bubble's parent. This allows you to quickly switch to and edit previous bubbles up the hierarchy.
