The statistics dialog in → gives you a statistical overview for a selection, a document or a whole project. It includes the number of words, LATEX commands/environments and also includes the number of characters for each type.
The statistics obtained can be copied as text or as a nicely formatted LATEX table to the clipboard.
When you select a text and open the statistics dialog, you get the statistics for the currently selected text. If you open the dialog without any text selected, the statistics for all opened files are shown. If you want to get statistics for the whole project, you can use → for an easy and quick way to open all source files of your project.
A note of caution has to be sounded about the accuracy of the numbers. We have included some logic to get a good estimate, e.g. K\"uhler gives one word and one command, with six and two characters respectively. But there are other combinations in which parts of commands are counted as words and vice versa. Please note that the algorithm was developed and tested for languages similar to English or German. So don't take the numbers for granted. If you write a report whose length has to be of a certain numbers of words or characters, please make some tests first in order to check whether Kile's accuracy satisfies your needs.
