APL uses a | APL uses a range of [[glyphs|special graphic symbols]] to represent most functions and operators. While keyboard mappings become [[mnemonics|memorized]] over time, entering APL characters can frustrate the [[learning resources|beginner]].

There are several convenient ways to enter the glyphs. | ||

Depending on whether you want the whole document to use the APL font or not, you may remove the command to set the main font. If you do so, APL glyphs will be rendered correctly inside code listings and similar environments, but not in the main body of the document. | Depending on whether you want the whole document to use the APL font or not, you may remove the command to set the main font.
