Controls
Mouse controls:
| Single-click chromosome | Display all the homologies of this chromosome |
| Single-click chromosome with Ctrl (Mac: Cmd) down | Select this chromosome for homology display (links -- if available -- show when two or more chromosomes selected) |
| Single-click background | Hide all homologies |
| Double-click chromosome | Expand chromosome to fill the screen vertically |
| Hold down Shift and drag mouse, then release | Zoom in on region outlined by panning |
| Hold down Shift and Ctrl (Mac: Shift + Cmd) and mouse drag on or next to chromosome | Highlight region of interest and display links in real-time (press ESC to start over) |
| Scroll mouse wheel with pointer over a genome | Scroll genome up or down |
| Scroll mouse wheel with Ctrl key held down | Zoom in /out |
| Mouse over feature on chromosome | Display names of features mapped to this location |

Reset buttons:
The main reset button on the toolbar
resets the zoom factor for all genomes to a value of 1 and restores the original view as seen after loading the data
(i.e. without any links or results showing). The reset button next to the zoom slider below the main
canvas resets the zoom for the currently selected genome only, without removing results or links.

Inverting chromosomes:
In cases where there are large scale inversions, inverting a chromosome can be useful for providing a better view of the synteny between a pair of chromosomes. To do this, right-click over the chromosome (with or without links selected) and choose “Invert chromosome” from the context menu.Back to top
Zoom control panel:
At the bottom of the main window there is a panel that contains controls which are applied to the currently selected genome. A genome is either selected automatically, through any operation involving clicking or mouseover on chromosomes in that genome, or manually by clicking on the genome's name in the name panel above the zoom control panel. The selected genome's name will be highlighted in red.The controls in this panel include:
- a zoom slider
- a spinner control for entering/modifying the maximum zoom factor
- a zoom reset button which resets the zoom only for the selected genome
- the "Always show all features" button which overrides the automatic suppression of features getting drawn at low zoom levels (see the view page for details)
- scroll buttons for scrolling the selected genome up and down
