Scope of Editing»

Edit Across Glyphs»

In situations where you have multiple glyphs visible at once, on the Sketchboard or in a Glyph Window, Edit Across Glyphs ensures that you can edit multiple visible glyphs at once. To edit one glyph at a time, turn off Edit Across Glyphs.

If Edit > Edit Across Glyphs is off (which is the default), then in the Glyph window:
* the active glyph is shown in detail with contours and nodes, and has a pale semi-transparent fill that can be changed in Preferences;
* inactive glyphs are shown filled, but without the details visible in the active glyph;
* you can only edit the active glyph, and change which glyph is active (by double-clicking on the other glyph) before you can edit another glyph.

If Edit > Edit Across Glyphs is on (because you have changed the setting), then in the Glyph window:
* all glyphs in the text are shown in detail with contours and nodes, and has a pale semi-transparent fill that can be changed in Preferences;
* you can edit across glyphs, selecting parts of multiple glyphs at the same time.

Edit Across Elements»

Edit Across Elements ensures that you can edit multiple visible elements at once. To edit one element at a time, turn off Edit Across Elements.

If Edit > Edit Across Elements is off (which is the default), then in the Glyph window you can only edit contours on the current element.

If Edit > Edit Across Elements is on (because you have changed the setting), then you can perform contour editing operations (using tools like Contour, Eraser, Knife) across multiple elements in the same glyph.

Edit Across Layers»

Edit Across Layers ensures that you can edit multiple visible layers (masters) at once. To edit contours on one layer at a time, turn off Edit Across Layers.

If Edit > Edit Across Layers is off (which is the default), then in the Glyph window you can only edit contours on the currently selected layer.

If Edit > Edit Across Layers is on (because you have changed the setting), then you can edit contours across different layers and masters within the same glyph (the Edit Across Elements option must be active as well) or even across glyphs (if Edit Across Glyphs is also active).
