Each toolbar button does exactly what its keys do, and its tooltip shows them. On a Mac, ⌘ works wherever Ctrl is written (⌘Z, ⌘S, ⌘C, ⌘-click), and Ctrl works too; redo is also ⌘⇧Z.
| Keys | What they do |

| Arrows | In math, move the cursor. On the page, move the red crosshair, or the selected regions. |
| Space | In math, select more of the expression, a step at a time. |
| Insert | In math, move the cursor to the other side of the selection. |
| Tab, Shift+Tab | The next or previous placeholder (■), then the next or previous math region. |
| Backspace, Delete | Delete before or after the cursor. On the page, take out the blank line above or below the crosshair. |
| Enter | Leave the math region. On the page, move the crosshair down a line, moving the regions below with it. |
| Escape | Leave the region. |
| Ctrl+Z; Ctrl+Y or Ctrl+Shift+Z | Undo; redo. |
