I have added 1/2 Foot Ceiling Height Cave Fonts to the Cave Font Download page at http://www.cavediggers.com/fonts i.e. .5, 1.5, 2.5, 3.5, 4.5, 5.5, 6.5, 7.5, 8.5, 9.5
The PDF Keymap is included in each Cave Font Download.
For Drawing Programs---Simply type the Cave Fonts somewhere in your cave map then adjust the font size to that which is most like what you will be using in your passages then drag the font onto your Symbols Palette! Then using it again is as simple as dropping it out of the symbols palette!
