Unable to Shift Tab to delete tab and go backwards

[gromul]

I'm used to tabbing forward and shift+tabbing backward, but in AkelPad 4.9.7 (x86) on Windows 8.1 x64, shift+tab also moves forward.

I tried adding IDM_EDIT_DELETE_TAB using the hotkeys plugin, but this doesn't work.

Any ideas how to fix this?

Thanks!

4166 Delete tabulation if several lines selected, otherwise insert tabulation.

Do you sure you select several lines?

Ok, I see that SHIFT+TAB works as expected if multiple lines are selected. How I would like TAB and SHIFT+TAB to work is the following:

1) Nothing selected: TAB to go forward and SHIFT+TAB to go back (delete tabulation). E.g. the user scenario is I changed my mind about this paragraph needing to be indented and switching to using DEL or BACKSPACE breaks the flow.

2) Something is selected in a single line:
TAB: instead of deleting selection, the selection is tabbed, same as in multiline TAB (if I want to delete selection, I have DEL and BACKSPACE).
SHIFT+TAB: instead of deleting selection, works the same as multiline SHIFT+TAB.

3) Column selection in multiple lines:
TAB: same as current operation
SHIFT+TAB: similar to current operation, but can also splice selection before non-selected characters.

I realize that 2 and 3 are not trivial to implement, but 1 is must have for me. If number 1 can't be done easily without additional coding, then fair enough.
