similar DOS Navigator's editor [closed]

"If you mean selecting and manipulating rectangular blocks of text instead of lines, then a few spring to mind:

Far's editor can do that; just hold Alt instead of Shift while selecting
Notepad++ can do it as well; just hold Alt+Shift but the implementation is horrible. For example, your block can't extend further to the right than the length of the current line (even though other lines in the block may be longer). In my eyes, this is a bug.
Visual Studio also allows this, using Alt+Shift again.
VS Code uses Ctrl+Alt to extend a selection down- or upwards, and normal Shift within the same line."

"How about gvim? You can easily copy and paste blocks using yy (yank) and p to paste.

For example, if you wanted to copy 3 lines starting on the line of the cursor, you'd first press Esc to ensure you were in command mode, then 3yy."
