-## Can I use Vi-Mode with ProDOS?
-Not currently. Everything works fine for the prompt itself, but

- 1. it interferes with DOS commands in a way I don't yet understand, and
- 2. I haven't written the (simple) bootstrapper program for it yet, just hacked it into place to test briefly.

 ## Problems and Short-Comings
 
  * The ability to go and grab content off the screen is lost now.
- * No PROdos support (yet).
  * 80-column mode is somewhat fragile, and occasionally annoying. This is due chiefly to the fact that 80-col `RDKEY` automatically a number of things that the standard firmware doesn't, and I wish it wouldn't. I may resolve these issues by avoiding `RDKEY` in the future, but for now I'm stuck with it.
  * It really wants the **d** and **c** commands from **vi**... and **y** and **p** for copy/paste would be nice too. I plan to add these soon.
  * Due to the way **a2vimode** detects and wrests away control from the firmware `GETLN` routine, there is a small-but-not-zero chance of mistaking some values on the stack for return addresses, that aren't, and consequently breaking some function up the call stack.
