Untab in nano: move a block of code to the left

Question

How can I "Untab", move a block of code to the left in nano?

In most gui editors shift+tab works but can't find anything for nano.

Answer 1

With an english keyboard-layout Ctrl + Alt + { should work to unindent tabs (untab) in Nano Text Editor.

If you use a keyboard-layout which needs Alt-Gr for curly braces, use ESC then { instead.

Answer 2

Manjaro,Year: 2022>> give "shift+tab" a try after you have mark"alt+a" your selected texts.
