Format your text

While editing an item, select some text and press a shortcut, or use the toolbar that appears above the selection:

Ctrl/Cmd + B — Bold

Ctrl/Cmd + I — Italic

Ctrl/Cmd + U — Underline

Ctrl/Cmd + Shift + S — Strikethrough

Ctrl/Cmd + E — Inline code

Ctrl/Cmd + Shift + H — Highlight

Ctrl/Cmd + Shift + M — Mute

Selecting “before Friday” and pressing Ctrl/Cmd + B, then Ctrl/Cmd + Shift + H, makes it bold and highlighted.
