Yes, I see it now. I only tested it with multiline blocks. But I find 
that behaviour a bit illogical. Why should the search dialog suddenly 
use the block as default (instead of the text at cursor) only because it 
consists of one line only? That makes no sense. I would want to use the 
text at cursor in *all* cases (independent from persistent blocks) 
because I may not even be aware that a block is still active. This way I 
have to think about this side effect whenever I use the search function.

Yes, the code tools commands to jump to BEGIN and END had the same keys. 
After I changed that it works now.

There seems to be 2 other code tools functions that change the 
persistent block: Jump to BEGIN or END. Afterwards the persistent block 
no longer exists and cannot be recovered with Ctrl+K,H nor can I jump to 
its former location with Ctrl+Q,B or Ctrl+Q,K.

> BTW column mode: should work the same as in non-persistent:

Yes, it works very intuitive. Here it's configured to use 
Alt+Shift+Cursor to select a column block while Shift-Cursor does it in 
standard mode.



Thanks again for adding this!
