Keyboard shortcuts

On macOS use Cmd where Ctrl is written.

The keys below are what the app starts with. Format ▸ Keyboard shortcuts… lists every one of them and lets you put an action on another key: click Change and press the keys you want. A shortcut needs Alt or Ctrl — a key on its own types a base in the sequence view — and the app refuses a key the browser keeps for itself or one another action already has, saying which. Default puts one action back, All back to their defaults the lot. Ctrl+S, Ctrl+F, Ctrl+Z, Ctrl+Shift+←/→ and the ranges (Alt+1…9, Alt+Shift+PageUp/PageDown) are fixed. Your changes are kept with the rest of the view's settings, in this browser.

Files

Keys	Action
`Ctrl+S`, `Ctrl+Shift+S`	Download GenBank (a working copy's changes are reviewed first)
`Alt+L`	Copy a share link
`Alt+1` … `Alt+9`	Bring the first … ninth open document forward
`Alt+0`	Bring the Bench forward
`Alt+W`	Close the document in front (its tab)
`Alt+Shift+PageUp`, `Alt+Shift+PageDown`	Move the document in front one tab left or right
`Ctrl+V` with nothing open	Open a pasted GenBank or FASTA record, or bare bases
`Alt+K`	Compare with another tab or a file (File ▸ Compare with…)
`Escape` in Export figure…	Stop an export under way (the dialog stays); again to close

Editing

Keys	Action
`A C G T …`	Insert a base at the cursor, or replace the selection
`Backspace`	Delete the base before the cursor, or the selection
`Delete`	Delete the base after the cursor, or the selection
`Ctrl+C`	Copy the selection with its features
`Ctrl+X`	Cut the selection with its features
`Ctrl+V`	Paste at the cursor or over the selection
`Ctrl+Z`	Undo
`Ctrl+Shift+Z`, `Ctrl+Y`	Redo

On the Bench, where there is no sequence to edit, Ctrl+Z and Ctrl+Shift+Z (or Ctrl+Y) undo and redo changes to the shelf.

Showing and hiding

Everything here is Alt and one key. Bare letters type bases in the sequence view and Ctrl belongs to the browser, so Alt is the modifier left for the view. In front of a protein, Alt+C, Alt+T, Alt+R and Alt+V do nothing, since a protein has no complement, translations, cut sites or map, and Alt+[ and Alt+] step through the tabs it has.

Keys	Action
`Alt+C`	Complement strand on or off
`Alt+T`	Translations under CDS features on or off
`Alt+R`	Cut sites on or off (the ticked enzymes are kept)
`Alt+G`	GC content track on or off
`Alt+E`	Edit marks off, and back to the baseline that was chosen
`Alt+S`	Collapse the sidebar to its rail, or bring the panel back
`Alt+V`	The next of the views: Sequence, Map, Both
`Alt+[`, `Alt+]`	The sidebar tab above or below (opens the sidebar)
`Alt+=`, `Alt+−`	Larger or smaller sequence text
`Alt+O`	Open the Format menu; Tab walks its rows, `←`/`→` a row's choices, Escape closes
`Alt+Y`	Open the Style menu for the selected bases (colour, size)
`Alt+U`	Open the Case menu for the selected bases (upper, lower)

Selecting and moving

Keys	Action
`← →`	Move the cursor one base
`↑ ↓`	Move the cursor one row
`Shift` + arrows	Extend the selection
`Ctrl+Shift+←`, `Ctrl+Shift+→`	Extend the selection a codon at a time
`Home`, `End`	Start or end of the row
`Ctrl+Home`, `Ctrl+End`	Start or end of the sequence
`Shift+click`	Extend the selection to the clicked position
`Ctrl+A`	Select all
`Escape`	Clear the selection
`Alt+N`	Select the next marked change
`Alt+Shift+N`	Select the previous marked change
`Alt+N`, `Alt+Shift+N`	In the alignment's large view: next, previous difference (a whole run, among those the Filter lets through); follows a rebound Next change
`Ctrl+F`, `Ctrl+G`	In the alignment's large view: find a motif; go to a position (not rebindable; Esc closes the form, then the window)
`Alt+T`	In the alignment's large view: Amino acids on or off (follows a rebound Translations)
`↑`, `↓`	In the alignment's large view, with the alignment focused: pick the sample above or below

Find

Keys	Action
`Ctrl+F`	Open find
`Enter`	Next match
`Shift+Enter`	Previous match
`Escape`	Close find

Map

Input	Action
Wheel, pinch	Zoom about the pointer
Double-click a feature	Zoom to fit it
Double-click elsewhere	Zoom in one step
Drag empty space, middle-drag	Pan when zoomed in

The Bench's product map takes the same, and a drag anywhere on it pans, since there is nothing on it to select.

Panes

Alt+B takes the keyboard to the next boundary between two panes (see Viewing); there:

Input	Action
`← →` or `↑ ↓`	Move the boundary a little; past a floor, fold away
`Page Up`, `Page Down`	Move it further
`Home`, `End`	Take it to either pane's floor
`Escape`	Back to where the keyboard was before `Alt+B`
Double-click the boundary	Put that boundary back where it was

Feature editor

In the editor under a feature in the Features tab (see Features):

Keys	Action
`Enter`	Save changes
`Escape`	Cancel; a feature just made with Add feature goes again

Help

Keys	Action
`?` (outside the sequence view)	Open this guide
`Escape`	Close it
