You can move, copy, or delete selected text.
You can increase or decrease indents in a selected text fragment. Select one or several text lines (if you select a single line, you have to select the end of the line; if you select multiple lines, it is enough to select only a part of each line) and then, on the main menu, point to Text, point to Block, and click Increase Indent or Decrease Indent.
Increasing an indent adds a tab character to each line. Decreasing an indent removes a tab character or an equivalent number of spaces from each line.
