Is it possible to create a glyph that will show up when a combination of keys are entered in with the keyboard?
For example, say I want the letter “f” to appear when I type “ph”
Or any glyph for that matter, just to be able to program that a certain glyph appears when two or more keys are typed together in sequence. Is this possible?
Yes, its possible by Adding OpenType Features to the font. However, not many applications support OpenType glyph substitutions.
If you enable the complex text features in Windows, Notepad will support glyph substitutions, e.g. converting f+ i to fi but WordPad and Word (AFAIK) do not, and neither does OpenOffice. I use macros or find and replace to make the substitutions manually although my fonts do include OpenType features.
