Key Strokes
Jalview has two distinct modes of keyboard operation - in 'Normal' mode, single keystrokes (including those shown next to menu items) provide short cuts to common commands. In 'Cursor' mode (enabled by F2), some of these are disabled and more complex 'Compound Keystrokes' can be entered to perform precise navigation, selection and editing operations.

The compound commands available in the Cursor mode are summarised below. Single letter commands can be prefixed by digits to specify a repetition number, and some more complex commands take one or more numeric parameters (prefixing the command key and separated by commas).
| Compound Command | Mode | Action (and parameter description) |
| 0-9 | Cursor | Begin entering a numeric parameter (p) or repetition number for a cursor movement or edit command. |
| , | Cursor | Separates one or more numeric parameters (e.g. p1,p2) for a command. |
| p1,p2 Return |
Cursor | Move cursor to a particular column (p1)
and row (p2) in the alignment. e.g. '5,6<Return>' moves the cursor to the 5th column in the 6th sequence. |
| pS | Cursor | Jump to the p'th sequence in the alignment. |
| pP | Cursor | Jump to p'th amino acid in current sequence. |
