- There are two buffers, IBUF (insert buffer) and FBUF (find
- buffer). They are used as a typing target for the actions
- described below. They both have a peculiar logic: when typing
- is expected to fill a buffer, an empty value means "reuse
- previous value". For example, typing "I foo I " inserts
- "foofoo".
-
- T ( n -- ): select line n for editing.
- P xxx: put typed IBUF on selected line.
- U xxx: insert typed IBUF on selected line.
- F xxx: find typed FBUF in block, starting from current
- position+1. If not found, don't move.
- i xxx: insert typed IBUF at cursor. "i" is to avoid shadowing
- core word "I".
- Y: Copy n characters after cursor into IBUF, n being length of
- FBUF. (cont.)
