Current Glyph This is the glyph that appears in the Outline and Glyph Ramp windows. The Tuples and Deltas windows are also coordinated to show relevant information about the current glyph. The current glyph number is displayed in the upper-left corner of the Outline window. The current glyph can be changed by typing a character in the Outline window, using the arrow keys in the Outline window (left arrow = previous glyph, right arrow = next glyph), double-clicking a glyph in the Palette window, or choosing "Select Glyph" from the menu.
Current Variation The Outline, Deltas, Kerning windows are all coordinated to show information about the glyph or font at the current variation coordinate. This coordinate can be set by choosing "Select Coordinate" (cmd-K), choosing an axis extreme from the Axis menu (cmd-1, cmd-2, etc.), double-clicking on a tuple in the Tuples window, or by double-clicking a glyph in the Glyph Ramp window.
Variation Coordinate This specifies the values for each of the font's variation axes. In this form, the value for each axis ranges from its specified minimum to maximum, which are defined in the Axes window.
Normalized Coordinate This is another way to specify the values for each variation axis. In this form, the value for each axis ranges from ­1 to +1, where ­1 corresponds to the axis' minimum value, 0 corresponds to the axis' default value, and +1 corresponds to the axis' maximum value.

Tuples A tuple for a glyph is a location in the font's variation space where the glyph has deltas. Normally this corresponds to extrema for each axis, a glyph can have deltas at any variation coordinate. NOTE: these coordinates are shown in normalized coordinates. Double clicking on a tuple set the current variation to that coordinate.
Deltas The Deltas window shows the deltas that are specifed for the current glyph at the current variation. Each delta consists of a point number and a movement in X and Y.
Instances Instances are the named coordinates that a user will see when the font is used in a word processor. Each instance consists of a name and a variation coordinate. Examples: ["Bold" (wght = 1.8, wdth = 1.0)] or ["Very Narrow" (wght = 1.0, wdth = 0.3)]
Axes The Axes window shows the definition of each variation axis. Each axis consists of a name, a 4-character tag (usually one of the standard tags registered with Apple), and the range of values along that axis that the font can display. NOTE: the default value for the axis represents the value that the font would have if it had no variations at all.
Outline This window displays the current glyph in the current variation. The display menu controls how the outline is displayed, and allows you to add overlays that show the original outline and/or the *** outline. To pan around, press SPACE and then click and drag. To zoom in, press cmd-SPACE and then click. To zoom out, press cmd-option-SPACE and then click.
