Full Screen
Switches to full screen mode, automatically hiding the menu bar, the status bar, the tool bar, the pattern folder and the scroll bars. To exit from this mode just hit the menu item's keyboard shortcut or any unassigned key. [Not supported on X11.]
Fit Pattern
Changes the scale and location so the entire pattern fits within the current view.
Fit Selection
Changes the scale and location so the entire selection fits within the current view.
Middle
Moves the origin cell (0,0) to the middle of the view.
Restore Origin
Restores the true origin. The origin cell can be changed by hitting "0" while the cursor is over the view — the cell under the cursor will become the new origin and its location will be displayed as 0,0. This can be handy for measuring distances or for saving a location and returning to it quickly by hitting "m".
Zoom In
Zooms in by doubling the current scale. If the scale is 1:16 then you can't zoom in any further.
Zoom Out
Zooms out by halving the current scale. Golly has an unbounded universe so you can zoom out as far as you like.
Set Scale
This submenu lets you set the scale from 1:1 to 1:16. A quicker method is to use these keyboard shortcuts: "1" for 1:1, "2" for 1:2, "4" for 1:4, "8" for 1:8 and "6" for 1:16.
Show Tool Bar
Shows or hides the tool bar at the left edge of the main window.
Show Layer Bar
Shows or hides the layer bar above the viewport window.
Show Status Bar
Shows or hides the status bar at the top of the main window.
Show Exact Numbers
If ticked then the status bar is made larger and exact numbers are displayed instead of using scientific notation.
Show Grid Lines
Shows or hides the grid lines. Use Preferences > View to turn off the bold grid lines or change their spacing, or to set the minimum scale at which grid lines should be displayed (1:4, 1:8 or 1:16).
Swap Cell Colors
If ticked then the colors used to display cell states are swapped. Use Preferences > Color to change these (and other) colors.
Buffered
If ticked then window buffering is used to avoid flicker, but it does slow down pattern rendering a bit so you might prefer to live with the flicker. Note that buffering is always used if grid lines are displayed or if a selection is visible.
This option is disabled on Mac OS X because windows are automatically buffered.
Pattern Info
Displays any comments in the current pattern file.
