This is a list of keyboard shortcuts that are available in Instantbird/Thunderbird with brief descriptions of what they do.
Note: Depending on your OS, the Command key may be Ctrl.
Command + F Find
Escape to put the conversation on hold
Command + W to close the current tab
Command + Shift + H for History (Show Logs)
Command + [Plus key], Command + [Minus key] - sets the Zoom level
Command + 0 - resets the zoom level to 100%. (Use the 0 key in the top row of the keyboard, not the 0 key of the numeric keypad.)
Scrolling the conversation
Shift + PgUp/PgDn scrolls a page up or down
Home/End or Alt + PgUp/PgDn scrolls to the previous/next section. Sections are
- the beginning and end of the conversation
- the beginning or end of a session (in the log viewer)
- the first non-context message
- the unread message ruler.
When the textbox is empty, the usual navigation keys (cursor keys, PgUp/Dn, ...) will scroll the conversation view also from the textbox.
The available shortcuts are listed in the menu next to the commands.
