Textbuttons now allow a selection too (like any textbutton in other UIs). By default, on activating a textbutton, the entire button text is selected when you enter the button. A single arrowkey or LMB click reveils the cursor then. Here's more user notes: LMB click: If inside the button, places the text cursor at the clicked position. If outside the button, confirms/finishes editing LMB drag: Selects the text between the start and end point of the drag. Backspace: Deletes selected text, or backspaces a character Shift Backspace: Deletes all, as before. Delete: Deletes selected text or forward deletes a character Shift LeftArrow: Extends the selection left Shift RightArrow: Extends the selection right LeftArrow: If there's a selection, move the cursor to the left edge of the selection, otherwise move the cursor left a character. RightArrow: If there's a selection, move the cursor to the right edge of the selection, otherwise move the cursor right a character. UpArrow/Home: Move the cursor to the beginning of the line DownArrow/End: Move the cursor to the end of the line Ctrl Left arrow and Ctrl Right arrow to jump between directory separators
