Upps

F8 works already as needed
for my suggestions No.1 and No.2 from my initial post above!
(It's even kinda "sticky selection" (No. 3), but not really)



How to:
- press F8 to set the starting point of an selection
- now use one (or more) of this movements:

* Ctrl+G GoTo e.g. Line 34

* Ctrl+F Find e.g. an word or an sign.
  Or RegEx ^$ to find next blank line (select paragraph)
  Tip: Even F3 works after F8. (e.g. Ctrl+F8 ,then F3)

* F2 go to next bookmark
* Shift+F2 go to prev bookmark

* use Arrow keys

* or just click somewhere else

And voila, all between is selected now.

You can even extent the selection by using
the same or an another moving command again.




There are some more F8 commands:

* Select Character command - F8
* Select Line command - CTRL+F8
* Select Vertically command - CTRL+Shift+F8
(it's a little bit tricky with bookmarks, but works:
  - press CTRL+Shift+F8
  - select the wanted columns at the first line
  - be sure to remember the end column number at the right(e.g.: 35)
  - go to next boomark (F2)
  - the selection line is at column 1 (the selection is
    at the left side of the start column.)
  - use now Ctrl+G to go to the remembered column '35' in this example.
  Or just use the right arrow key.)
