It displays a single line of text and lets the user edit it. Normally it is drawn with an inset box and a white background. The text may contain any characters, and will correctly display any UTF text, using ^X notation for unprintable control characters. It assumes the font can draw any characters of the used scripts, which is true for standard fonts under MSWindows and Mac OS X. Characters can be input using the keyboard or the character palette/map. Character composition is done using dead keys and/or a compose key as defined by the operating system.
Mouse button 1 | Moves the cursor to this point. Drag selects characters. Double click selects words. Triple click selects all line. Shift+click extends the selection. When you select text it is automatically copied to the selection buffer. |
Mouse button 2 | Insert the selection buffer at the point clicked. You can also select a region and replace it with the selection buffer by selecting the region with mouse button 2. |
Mouse button 3 | Currently acts like button 1. |
Backspace | Deletes one character to the left, or deletes the selected region. |
Delete | Deletes one character to the right, or deletes the selected region. Combine with Shift for equivalent of ^X (copy+cut). |
Enter | May cause the callback, see when(). |
Windows/Linux | Mac | Function |
^A | Command-A | Selects all text in the widget. |
^C | Command-C | Copy the current selection to the clipboard. |
^I | ^I | Insert a tab. |

Insert a Line Feed. (Similar to literal 'Enter' character) |
^L | ^L | Insert a Form Feed. |
^M | ^M | Insert a Carriage Return. |
^V, Shift-Insert |
Command-V |
Paste the clipboard. (Macs keyboards don't have "Insert" keys, but if they did, Shift-Insert would work) |
^X, Shift-Delete |
Command-X, Shift-Delete |
Cut. Copy the selection to the clipboard and delete it. (If there's no selection, Shift-Delete acts like Delete) |

Undo. This is a single-level undo mechanism, but all adjacent deletions and insertions are concatenated into a single "undo". Often this will undo a lot more than you expected. |
Shift-^Z | Shift-Command-Z |
Redo. Currently same behavior as ^Z. Reserved for future multilevel undo/redo. |
