Keys and gestures
Drag on the grid
Draw a selection box.
Drag inside a selection
Lift that block and move it. It drops when you click elsewhere.
Alt / + drag inside a selection
Leave the original behind and move a copy. On a block that is already lifted, this stamps a copy and keeps moving, so you can lay down a row of identical boxes.
Shift + drag
Start a fresh selection even on top of one you already have.
Arrow keys
Nudge the selected block one cell. With nothing selected, move the caret.
Shift + arrows
Resize the selection box.
Enter or Esc
Drop the block where it sits.
Ctrl/⌘ + C X V
Copy, cut and paste as a rectangle. Pasted text arrives as a floating block you can position.
Ctrl/⌘ + D
Duplicate the block in place.
Ctrl/⌘ + Z
Undo. Add Shift to redo.
Ctrl/⌘ + A
Select everything you have drawn. Add Shift for the whole canvas.
Delete
Erase inside the selection.
Typing
Overwrites the character at the caret. Nothing reflows.
Shift + drag with Line
Straight run instead of an elbow. Alt flips which way the elbow turns.
Opaque blocks
On, a moved block carries its own blank space and covers what is underneath. Off, blanks let the drawing below show through.
