Just received am email from Ben Willmore, he had some good tips.
Since I'm new to version 7 I really appreciated knowing this stuff:
So Here goes tips according to Willmore:
There are a few things that I don't like about the default setup of
Photoshop 7.0. The first one is the way the Brushes palette looks when
accessing it from the Options Bar at the top of your screen. It
defaults to showing a brush stroke preview, which I think takes up too
much space. So, to get things back to the way there were in 6.0, click
on the arrow that shows up in the upper left corner of that Brushes
palette and choose Small Thumbnail. Then to access those brushes, you
can right-click (Win), or Control-click (Mac) on your image. To choose
a brush and dismiss the palette at the same time, double-click on the
brush you'd like to use.
In addition to the standard Brushes palette in the Options bar (what I
like to think of as the "lite" edition) Photoshop 7.0 has introduced a
second, and entirely separate Brushes palette. This other palette (the
"I'll take everything" edition) gives you a ton of new options, and
can be accessed by choosing Window>Brushes. This is where you go to
change all the settings related to a brush (as apposed to just
choosing a preset brush). This palette has the same affliction as the
Options Bar version, so choose Small Thumbnail from the side menu of
the Brushes palette. The, if you like those brush stroke previews
(they are useful for the more unusual brushes), just hover over one of
the brush presets ( but don't click) until the tool tips show up and
then run your cursor over all the brushes to see a preview at the
bottom of the Brushes palette.
Now let's move on to working with Layers. Let's say you have a
document that has dozens of layers and you need to delete six of them.
Well, in either Photoshop 6.0 or 7.0, you can link those layers
together by clicking on the small indent that shows up to the right of
the eyeball icon on each layer. Then you can Command-click (Mac), or
Ctrl-click (Win) on the trash icon at the bottom of the Layers palette
to delete all the layers that are linked together! In earlier versions
you had to use that trick, but there wasn't a menu choice to
accomplish the same thing, but now in 7.0 you'll find a Delete Linked
Layers choice on the side menu of the Layers palette. Also, in 7.0,
they've added a Delete Hidden Layers command to the same menu, which
will trash all the layers that have the eyeballs turned off.
When using the Eyedropper tool, you can usually only grab colors from
the open Photoshop images, but in 7.0, you can click within an open
Photoshop image and then drag outside of that image to choose a color
from any part of your screen. I use that technique to sample colors
that I like from different web pages. As long as the browser window is
visible, then you should be able to drag to it to pick up colors.
Ok, now here's one for you web folks. If you click on the bottom-most
icon in Photoshop's Tool palette, you'll be transferred over to Adobe
ImageReady. Once you get there, create a new document with a
transparent background and then type "duckerboard" and see what
happens to the checkerboard that usually indicates an area that is
transparent. To get things back to normal, just type that phrase a
second time.
