BUGS:
|
|
- Help menus with WordStar commands (C-j just calls help-for-help)
|
|
are not implemented
|
|
- Options for search and replace
|
|
- Show markers (C-k h) is somewhat strange
|
|
- Search and replace (C-q a) is only available in forward direction
|
|
|
|
No key bindings beginning with ESC are installed, they will work
|
|
