What button does this?

[Eraser]

I don't know what button I pressed or what I did, but suddenly my GtkRadiant 1.4 is showing the dimensions of the brush I've selected (next to the brush). I've looked in the menu options but can't find which option enables this. I find it somewhat annoying. Does anyone know where I can enable/disable this?

is it a blue square with x,y,z stuff going on? or the red brackets?

if it's the first one, I think you press q

if it's the other one....reset your preferences? I'm not sure about that one.

It's the red brackets. It shows a horizontal red line and a vertical red line next to the brush with the dimensions next to those lines.

It's "J". Shadow recently told me.

Why would you disable it?

I thought J is switching through the 3d selections.

Because it's annoying and not very useful to have in the screen all the time IMO.

Yeah, I don't like it either, but I could see how some may have use for it.

Its Q in my version, oddly. But it doesn't always work. Sometimes ,you can press it and turn it on/off at will. Othertimes you need to press it, then quit the editor and it will work... Very odd.

i hate that

i accidentally turned on caret browsing in FF while cleaning my kb, and had to press every function key to undo it (it's F7 fyi), which was funnnn

Especially useful for Defrag-Mappers. Creating Overbounce-heights would be a pain in the ass without that feature.

I think its also useful for general use - building the map according certain distances will surely improve the gameplay (jump heights, possibilities for rocketjumps, plasmajumps, circle jumps...).
