| Mouse button 1 | Moves the cursor to this point. Drag selects characters. Double click selects words. Triple click selects all text. Shift+click extends the selection. When you select text it is automatically copied to the clipboard. |
| Mouse button 2 | Insert the clipboard at the point clicked. You can also select a region and replace it with the clipboard 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. |
| Enter | May cause the callback, see when(). |
| ^A or Home | Go to start of line. |
| ^B or Left | Move left |
| ^C | Copy the selection to the clipboard |
| ^D or Delete | Deletes one character to the right or deletes the selected region. |
| ^E or End | Go to the end of line. |
| ^F or Right | Move right |
| ^K | Delete to the end of line (next \\n character) or deletes a single \\n character. These deletions are all concatenated into the clipboard. |
| ^N or Down | Move down (for Fl_Multiline_Input only, otherwise it moves to the next input field). |
| ^P or Up | Move up (for Fl_Multiline_Input only, otherwise it moves to the previous input field). |
| ^U | Delete everything. |
| ^V or ^Y | Paste the clipboard |
| ^X or ^W | Copy the region to the clipboard and delete it. |
| ^Z or ^_ | 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+move | Move the cursor but also extend the selection. |
| RightCtrl or
Compose | Start
a compose-character
sequence. The next one or two keys typed define the character to
insert (see table that follows.)
For instance, to type "á" type [compose][a]['] or [compose]['][a]. The character "nbsp" (non-breaking space) is typed by using [compose][space]. The single-character sequences may be followed by a space if necessary to remove ambiguity. For instance, if you really want to type "ª~" rather than "ã" you must type [compose][a][space][~]. The same key may be used to "quote" control characters into the text. If you need a ^Q character you can get one by typing [compose][Control+Q]. X may have a key on the keyboard defined as XK_Multi_key. If so this key may be used as well as the right-hand control key. You can set this up with the program xmodmap. If your keyboard is set to support a foreign language you should also be able to type "dead key" prefix characters. On X you will actually be able to see what dead key you typed, and if you then move the cursor without completing the sequence the accent will remain inserted. |
