190 BUGS:
|
|
|
191 - Help menus with WordStar commands (C-j just calls help-for-help)
|
|
|
192 are not implemented
|
|
|
193 - Options for search and replace
|
|
|
194 - Show markers (C-k h) is somewhat strange
|
|
|
195 - Search and replace (C-q a) is only available in forward direction
|
|
|
196
|
