Mouse

jOtter works fully from the keyboard, but the mouse is there when you want it.

Action	Does
Click a cell	Select it
Click inside the cell you are editing	Move the cursor there
Double-click a cell	Edit it in insert mode at that spot
Wheel	Scroll the notebook, or the long output under the pointer
Shift + drag	Select text with your terminal’s own selection

A wheel gesture sticks to what it started on: if you start scrolling the notebook and the pointer passes over a long output, the notebook keeps scrolling.

Because jOtter captures mouse events, your terminal’s normal drag-to-select doesn’t reach it. Holding Shift bypasses this in almost every terminal. To copy a whole cell, yy is quicker: it puts the source on the clipboard.
