- 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.
-
- <PICK+CLEAR> clears the current pick buffer, and places the current
- line in the buffer. The line is then deleted from the file.
-
- <PICK+APPEND> appends the current line to the current pick buffer. The
- current line is then deleted from the file.
-
- <COPY> 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> 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 operations 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> is like the <MARK> operation, except it defines a
- rectangular block. This is useful for manipulating columns.
-
- <SEARCH & MARK> 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> 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).
