ROPE];
like InsertChar, but for entire rope
InsertLineBreak:
PROC;
insert a CR and then copies blanks from front of previous line
BufferedInsertChar:
PROC [char:
CHAR];
Exactly as InsertChar, but returns immediately, forking a repaint process.
This is intended for use with user type-in. See TEditBufferedInputImpl
BufferedInsertText:
PROC [text:
ROPE];
Exactly as InsertChar, but returns immediately, forking a repaint process.
This is intended for use with user type-in. See TEditBufferedInputImpl
WaitForInsertToFinish:
PROC;
returns after buffered input has completed
BackSpace:
PROC [count:
INT ← 1];
Deletes the character preceding the insertion point and repaints the document
BackWord:
PROC [count:
INT ← 1];
Deletes the word preceding the insertion point and repaints the document
DeleteNextChar:
PROC [count:
INT ← 1];
Deletes the character after the insertion point and repaints the document
DeleteNextWord:
PROC [count:
INT ← 1];
Deletes the word after the insertion point and repaints the document
