I haven't tried it, but that sounds like it should be the TAB key. But this text box may not recognize the TAB key.
Ok, the tab key will not work in this text box. It switchs you from button to button instead. Also I think this box removes extra spaces unless you use the [pre ] and [/pre ] controls that are for tables. Note, I put a space in the pre and /pre so you could see them you don't want the spaces.
TEST TEST there should be ten spaces between the two tests.
What program are you using to write your text? The tab key works with most text editors that I know of.
If you're talking about indenting on IHUB you'll have to use fixed fonts. To use fixed fonts you have to surround the part you want fixed with [ pre ]whatever you want typed[ /pre ]
Leave out the spaces before and after "pre" on the front and "/pre" on the end. I included them to get it to get it to show in this post. Below is an example. The first line is typed normally. The second line is what you get if you hit the spacebar 4 times and then typed "indented" (surrounded by the brackets and pre)
