Persistent blocks:
Keyboard:
- Ctrl-K + B or Ctrl-K + Ctrl-B will define the beginning of the
block. If it is before the end of the block the block is shown even if
it was hidden before.
- Ctrl-K + K or Ctrl-K + Ctrl-K will define the end of the block. If
it is after the end of of the block the block is shown even if it was
hidden before.
IMO there is no requirement that ^BB must reside before ^BK in the text
(equivalent to the mouse UI).
- Ctrl-K + H or Ctrl-K + Ctrl-H will hide\unhide the block.
- Shift-Up / Shift-Left / Shift-PgUp / Shift-Ctrl-Home /
Shift-Ctrl-Left / Shift-Home:
1) If the cursor was not at the beginning of the block then a new
block is defined and the old one removed. The block end is at the
original cursor position and the block beginning is at the new cursor
position.
2) If the cursor WAS at the beginning of the block then the block
is extended by placing the block beginning at the new cursor position.
- Shift-Down / Shift-Right / Shift-PgDn / Shift-Ctrl-End /
Shift-Ctrl-Right / Shift-End
1) If the cursor was not at the end of the block then a new block
is defined and the old one removed. The block start is at the original
cursor position and the block end is at the new cursor position.
2) If the cursor WAS at the end of the block then the block is
extended by placing the block ending at the new cursor position.
IMO it is (or should be) much simpler: When the cursor was not on ^BK,
the ^BB is set to the old cursor position. Then ^BK is set to the new
cursor position.
Mouse:
- The mouse works similarly. Dragging the mouse with the left button
pressed will either define a new block if the start position was not at
the block start (up) or end (down). If the drag start position was at
the block start when moving up or at the block end when moving down the
the block is extended.
IMO the same as with the keyboard, i.e. depending on the previous
position of ^BK. ^BB is set when the mouse button is pressed without
Shift (new block), else ^BB is unchanged. Then ^BK follows the mouse,
until the button is released.
