- BLOCK COMMANDS
-
- There are ten "pick buffers" which you can use to save text when you
- are cutting and pasting text. The default buffer is number 0. To
- change the number of the current pick buffer, use the <CHG PICK
- BUFFER> command (the CTRL F7 key).
-
- <PICK+CLEAR> (the F8 key) clears the current pick buffer, and places
- the current line in the buffer. The line is then deleted from the
- file.
-
- <PICK+APPEND> (the SHIFT F8 key) appends the current line to the cur-
- rent pick buffer. The current line is then deleted from the file.
-
- <COPY> (the SHIFT F9 key) does the same as <PICK+CLEAR> except the
- current line is NOT deleted from the file.
-
- All three of the above commands may take an optional count (for
- example, <ESCAPE> 3 <PICK+CLEAR> will pick and delete the next three
- lines). There are ten pick buffers, numbered 0 through 9. Buffer 9 has
- a special use, in that it stores lines and blocks that you have
- deleted with either the <DELETE LINE> command, or a delete block
- operation. The <UNDO> command looks in buffer 9 for lines to be
- reinstated. Buffer 0 is the default buffer.
-
- <MARK> (the F7 key ) defines a block of text to perform an operation
- on. Move to start of the block and press <MARK> a grey rectangle will
- be shown where you marked the text. Then move to the end of the block
- and press <MARK> again. The entire block will be highlighted. You are
- prompted for the operation to perform on the block. The current opera-
- tions are pick & clear, pick & append, copy, delete, write to a file,
- change the case, or change the format block associated with those
- lines. If you want to abort the operation, press <CTRL> D.
-
- <RECT MARK> (the SHIFT F7 key) is like the <MARK> operation, except it
- defines a rectangular block. This is useful for manipulating columns.
-
- <SEARCH & MARK> (the ALT F7 key) allows you to define a block from the
- cursor position up to and including a certain character. To mark off a
- sentence, press '.' (or the ending punctuation character). To mark off
- a paragraph, press <RETURN>. To abort the operation, press <CTRL> D.
-
- <PUT> (the F9 key ) allows you to take the contents of any one of the
- ten buffers and place it in your text. You are asked if you want to
- insert the text above the cursor, insert the text to the right of the
- cursor, or overlay the text at the cursor position (only if you used a
- <RECT MARK> to extract a column).
