Control-Left and Control-Right moves the caret a word at a time. Holding down Shift in addition to the above extends the selection a word at a time.
A single word can be selected by double-clicking with the mouse, or using the Edit>More Selection>Select Word command (shortcut: Control-E W). A selection that begins and ends on word boundaries can be created by double-clicking and dragging.
Control-Backspace and Control-Delete deletes the word before or after the caret, respectively.
Edit>Word Count displays a dialog box with the number of characters, words and lines in the current buffer.
Edit>Complete Word (shortcut: Control-B) locates possible completions for the word at the caret, first by looking in the current edit mode's syntax highlighting keyword list, and then in the current buffer for words that begin with the word at the caret. This serves as a very basic code completion feature.
If there is only one completion, it will be inserted into the buffer immediately. If multiple completions were found, they will be listed in a popup below the caret position. To insert a completion from the list, either click it with the mouse, or select it using the Up and Down keys and press Enter. To close the popup without inserting a completion, press Escape. Typing while the popup is visible will automatically update the popup and narrow the set of completions as necessary.
