Every shortcut in the editor, grouped the way the editor's own shortcut sheet groups them. The tables are generated from the commands the editor registers, so they always match the editor. Press F1, or choose Help › Keyboard shortcuts, to see the same list in the editor, including any shortcuts you changed.
The shortcut sheet in the editor, with a search box.
Change a shortcut
Open Edit › Settings… (Ctrl+,), go to the Keyboard page, click a shortcut and press the new keys. The editor points out conflicts with other commands. See Editor settings.
Some tools share a key, such as E for Rotate and for the tile Eraser. A key picks the tool of the group you are working in: after W, E rotates; after B, E erases. The tile tools only respond while a map is being edited.
While a tile tool is active, Z and Shift+Z rotate the brush or stamp, X and Y flip it, and Ctrl+C, Ctrl+X, Ctrl+V and Delete copy, cut, paste and delete selected tiles. See Painting tools.
These keys belong to the game, not the editor. They work in the Game panel during play mode, in the player and in development builds of an exported game.

Keys without Ctrl or Alt never reach the editor while a text field has focus, so typing a name never switches tools. Neither do Ctrl shortcuts that act on the selection, such as Ctrl+D.
