About selecting brushes:
This is what I was saying in this thread (select inside):
(Brush texture doesn't matter)
As you can see there are other ways to select brushes too:
Inside: self explanatory, the brushes that are inside the box will be selected
Touching: for example, if you want to select 4 brushes which are far away eachother, like this:
Make a brush that will TOUCH each of them, and do right click -> select -> touching. All the brushes which are touching the one you made will be selected (and that which you made will be deleted).
Targetname: if you've got 1000 objects with the same targetname (let's suppose we are going to select teleport triggers), select just one of them, and do right click -> select -> targetname. All the brushes with the same targetname will be selected.
(If you want to go further, go to "Selection" (menu bar) -> Select by Key/Value: Insert the exact key/value and the brush/brushes with those parameters will be selected.)
Select by classname ("Selection" -> "select by classname"): this will select all the entities which are the same class. For example, we've got 20 triggers, 10 of them are trig_use touch. If we want to select just the trigs which are "trig_use_touch", go to selection->select by classname, and all of the entities which are "trig_use_touch" will be selected.
I don't know what "Select partial tall" or "Select complete tall" do, but I have never used them. If you guys know something about it, add the info
