What developers can do

• Design your application without gui in mind first

• Logical order, just like CSS ☺

• Provide equivalent text applications, e.g. based on the same shared libraries

• For text application, put the cursor in a sane place

• To guide screen readers

• Take users suggestions into consideration

• E.g. bracketed links in text web browsers

• If you're crazy enough, test it yourself!

• gnome-terminal+brltty / accerciser / gnome-orca
