Example: searching the word "class" across 790 C++ header files.
Search words as you type, or by clicking on them. Fly through search results by the turn of your mousewheel. Copy text, and create bookmarks with the same ease. If you have to read through many small ASCII text files, e.g. source code, this tool allows text analysis at extreme speeds.
For example, to search a word, forget about opening a dialogue, setting options, clicking through results lists to open one result file after another. No, just type the word - and land within the first matching line in the first matching file, instantly. Then, if you see another word of interest, don't even type it - click on it! And again, you will land at the first match for this word, instantly, no matter in what file.
By default, you jump from result to result in the normal text. Even more efficient is the filtered view: click on the large "F" button at the right bottom to show only the text lines containing the search result.
One step more extreme is the Auto Filter: by right-clicking on the "F" button, it turns into "A", as in the example at the top. Now, whenever you type a word, filtering is activated instantly, showing only the result lines. Now, to read a text part of interest, just click into one of the result lines. In the example above, we click on "class nsIContentSerializer", so this text area is unfolded:
allowing instand reading through that area. To re-enter the filtered overview, just press CONTROL+A or (with active auto filter mode) type another search term.
