Bold a cell
Ctrl+B (or the toolbar Bold button) toggles bold on the selection.
What it does
Select cells and press Ctrl+B — or click the Bold (B) button in the toolbar — to toggle bold. Bold is presentation, separate from the cell's value: bolding =A1+B1 styles the number without touching the formula. It undoes and redoes like any other edit.
Verified behavior
Matches Google Sheets: In Google Sheets, Ctrl+B toggles bold on the selected cells. Bold is a presentation attribute independent of the cell's value or formula, and it undoes/redoes like any edit. Toggling again removes it.
Ctrl+B bolds the selected cell
Given
- A1 =
hello
When I click A1, then press Control+b
Then
- A1 is bold
Ctrl+B a second time removes bold
Given
- A1 =
hello
When I click A1, then press Control+b, then press Control+b
Then

Undo and redo edits
Ctrl+Z reverts the last change; Ctrl+Y (or Ctrl+Shift+Z) re-applies it.
Align cells and wrap text
Horizontal (left/center/right) and vertical (top/middle/bottom) alignment plus text wrap are per-cell format attributes; the toolbar sets them (Ctrl+Shift+L/E/R for horizontal), an explicit alignment overrides the type-based default, and a wrapped cell grows its row to fit its lines.
