QWERTY more and Dvorak more are keyboard layouts that I made for Mac OS X that add a bunch of Unicode symbols to the keyboard. Intended audience is those who use Mac OS X, are already familiar with entering special characters on Mac, and regularly need to type other Unicode characters (that are similar enough to the ones I type). The letters and numbers are the same as ordinary QWERTY/Dvorak; rather, more symbols have been added that use the Option key. Furthermore, non-redundant symbols using the Option key haven't been changed. Most of the new symbols require two keystrokes.
Symbols added include:
A keyboard layout for typing one of my conlangs, Súiⱥcúili. It's based on Dvorak, except that it has the letters i and o reversed, and letters not used in Súiⱥcúili are replaced with ones that are. Some of the punctuation is also moved around. Available for Mac OS X and also for Vim.
These are keyboard layouts to make it easier to type in the International Phonetic Alphabet. There are two layouts available, one based on QWERTY, the other on Dvorak. By default, these will function as a normal keyboard; however, if Caps Lock is on, instead of typing capital letters, it'll type letters in IPA.
