Multiline text selection messed up.

Multi-line text selection of only space/tab characters results inconsistent or at least quite startling and I argue quite un-useful behavior. Used to be rather useful and quite time-saving.

• pressing tab indent of all lines, not inserted at the multi-line caret location - seems circumstantial | erratic when it works vs when it indents the whole lot.
• pressing space will correctly insert a space at the caret location. 
• pressing space then tab will correctly insert a space and then tab at the caret location. 

Selecting a 1char wide selection tabs everything instead of inserting a tab. This is a rather time consuming affair to now tab things into place line by line.

Adding insult to injury, actually selecting whole lines and pressing tab, indents the lines as expected, but now also deselects automatically! So now every indentation increment requires re-selecting the lines every tab press!

You cannot also ALT-TAB the same block you just chose - because creator threw your only just acquired selection away.

You cannot hold ALT to begin writing in any position anymore, particularly noticeable for multi-line block uniform position end of line closures etc but even painful just for single lines. Especially frustrating that the caret moves itself to the end of the lines current max char#. Multi-line caret # selection again, is not at all consistent and results in staggered char indexes across lines if the desired index is > line max char index.
