Screenshots
Screenshots are an essential part of any software documentation.
For PC/Windows users, the PRT SCR key is what you hit to take a snapshot of the screen. This is located somehwhere near or above the Backspace key (You probably don't need to press shift). Once you hit that key, the screenshot will be copied into your clipboard, ready to paste into MSPaint (the default windows program) or any other graphics editor of your choice.
Style Guide for screenshots.
Filenames and formats
1. All screenshots should be saved and uploaded as a (pick yer poison) file.
2. The filename for the screenshots should start with the pagename of the page it is intended for (or the first 20 odd characters anyway) using dashes or underscores for spaces.
Cropping and Sizing
1. Whatever it is that you are trying to depict - show the whole thing / table / module / screen.
If it's something that's very large, like the admin menu, then showing the whole thing is probably not necessary. In some cases, (quiz creation) showing the whole page can create huge images. Do use common sense and be ready to trim things up if necessary
However, you may want to zoom if you're showing the smaller part of a whole, such as the left menus
Highlighting and emphasis.
1. Use the paintbrush with and set the paint color to red.
2. circle (by hand if you can do it neatly) whatever it is you are emphazising.
