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" shadows core word. Use
|
|
"i" to access it.
|
|
X ( n -- ): Delete X chars after cursor and place in IBUF.
|
|
E: Run X with n = length of FBUF.
