In addition to the Windows-mouse selection of text with the mouse, this editor supports the Wordstar block commands. Blocks marked by Wordstar commands are not transient. The marking of the block disappears only if you delete the block (^KY) or if you hide the block (^KH). Marking a block by using the mouse will be transient: clicking into the text with the mouse will let go the block. Nevertheless, you can mix CUA commands (like Ctrl-Ins for "copy block into clipboard") with Wordstar Ctrl commands.
^KB: mark the beginning of the block
^KK or ^KE: mark the end of the block (Wordstar only ^KK)
^QB: jump "quick" to the beginning of the block
^QK: jump "quick" to the end of the block
^KC: copy the block to the cursor
position
^KV: move the block to the cursor position
^KR: read file into block at the current cursor position
^KW: write block into file
^KY: delete block
^KH: hide/show block marking
^KM: running text to comment lines and reverse
