Shift-Tab Not Working

[ITFlip]

Pressing the Tab key tabs to the right as expected.
Pressing Shift-Tab also tabs to the right when it should tab to the left (as per the printing on my keyboard).

Does Ctrl-Shift-M do the same thing?
Thanks!

Thank you for your report. Could you please let us know where exactly you are pressing Shift+Tab — for example, inside a table, in a bulleted/numbered list, or in regular body text? The expected behavior differs depending on the context:

• In a table: Tab moves to the next cell, and Shift+Tab should move to the previous cell.
• In a numbered list: Tab increases the indent level, and Shift+Tab should decrease it.
• In regular text: Shift+Tab behaves the same as Tab and inserts a tab character.

Regarding Ctrl+Shift+M — in TextMaker, this decreases the left paragraph indent, which is a different action from Shift+Tab. So no, it does not do the same thing.

Thank you for the clarification regarding how Tab and Shift-Tab work in various situations. It seems everything is working as intended - my confusion came from my lack of familiarity with the Paragraph Indenting features I encountered in Regular Text (this behavior is set in Options on the General tab as "Set left and first-line indent with Tab and Backspace keys"):

• With your cursor at the beginning of a blank line or at the beginning of a line of text: Tab increases the indent of the first line of the paragraph. Subsequent presses of Tab indents the entire paragraph. Pressing Shift-Tab or Backspace once removes the indent of the first line, subsequent presses of Shift-Tab or Backspace decrease the indent of the entire paragraph.

• If you place your cursor at the end of a line of typed text, Tab and Shift-Tab both insert a tab character and move your cursor one tabstop to the right. Pressing the left and right cursor keys will move your cursor to the left and right from tabstop to tabstop. Pressing Backspace will delete the tab character and move your cursor to the left to the previous tabstop.

In any case, the behavior is consistent across all the versions of TextMaker I tested (2024 Linux & Windows; 2026 NX Beta Linux & Windows) with both new and existing documents.
