With thanks to "quarantined" for finding a bug in the search with single characters, I have fixed that bug then fixed a couple of very obscure bugs that followed from it. The reason for some of the complexity is that the default handling of a number of capacities in the rich edit control had to be over ridden so that the paragraph indent remained simple and easy to use. When text is selected the TAB key is disabled, when there is no selection, it replaces tabs with spaces so the text can be used in other contexts without having to account for different TAB sizes.
The inline technique for the left and right indent control is fast enough to no longer need preset indent and if you need to left align the selected text, just use the left arrow key to align the text to the margin then set whatever indent is needed.
Same as before, it will load files in excess of 500 meg, it is genuinely fast and handsome enough. It is no joy to modify but it is the nature of the beast. As before it is copyright software to prevent it being included in shovel ware and it is presented complete with full source code for members to use, modify or use its components.
