Navigation¶

Mouse and wheel¶

  • Mouse wheel: zoom in and out

  • Shift + mouse wheel: pan left and right

  • Horizontal mouse wheel: pan left and right

  • Drag on the map track: move the current viewport

  • Click on the map track outside the current viewport: jump to that region

  • Double-click empty space in the genome or annotation tracks: center that position in the window

In comparison view:

  • double-click in a genome axis/coordinate band to center that position in the visible genome area

  • double-click a match to align that match in the view

  • click and drag across a genome row to select a comparison interval

  • right-click a contig in a map strip to reverse-complement or reorder that contig

Trackpad¶

  • Horizontal two-finger swipe: pan

  • Pinch: zoom

  • Vertical swipe zoom can also be enabled in settings

Trackpad and wheel sensitivity can be changed in the settings panel.

Toolbar controls¶

The toolbar at the top provides (keyboard shortcuts in brackets):

  • open/close settings panel (s)

  • switch between browser and comparison view

  • jump to start (shift-left arrow)

  • pan left (left arrow)

  • pan right (right arrow)

  • jump to end (shift-right arrow)

  • zoom out (-)

  • zoom in (+)

  • search (ctl/cmd-f)

  • go to position (ctl/cmd-g)

  • screenshot export as SVG

  • clear current browser/comparison state

The shortcut are shown also shown in the tooltips (ie on mouse hover) inside the app.

Selection¶

  • Click a feature to select it

  • Click a read to select it

  • Click a variant to select it

  • Double-click a feature or read to open its detailed panel action

  • Double-click a variant to open its detailed panel action

  • Click and drag across the genome / annotation area to select a genomic region

  • In comparison view, click a match to select it

  • In comparison view, click and drag across a genome row to select a region and list overlapping matches

Selection in genome view just selects the region for now; in future it will allow for things like copying and pasting highlighted sequence.

Temporary save/jump views¶

Pressing shift+1 will save the current position and zoom level. Pressing 1 later will jump back to that position/zoom. This works for the numbers 1-9, giving nine save slots.

Browser mode and comparison mode keep separate temporary slot banks.

Contig menus¶

Contig map strips also support a right-click menu for contig-level actions.

See Contig Actions for reverse-complement and reorder operations in browser mode and comparison view.
