For your profile:
You can use the editor MFC provides to make a very nice profile. If you want to add some line breaks (as though you were using an enter button), just put "<br>" every time you would press the enter button. So to have a blank line between paragraphs, use <br><br>/
Lastly, if you're putting enough text that the little text boxes they provide don't show even half of it, save your text in an outside source for easier editing. I use a text document (you can find notepad), but anything that saves words and lets you copy-paste the words will work.
In case someone reading doesn't know these, here's some important keyboard shortcuts. I'm going to assume that at some point this will be read by someone who has no notion about these things, so please be patient if you already know some of this.
In a keyboard shortcut, the way it's written is ctrl + (a letter). The + means you press both keys at the same time. The awesome thing about the ctrl key is you can press and hold it, then press the key for the shortcut you're using without having let go of the ctrl key.
Basic ones to try:
ctrl + a (highlights all text in the document/window)
ctrl + c (creates a clipboard copy of all highlighted text, which can then be pasted in any program)
ctrl + v (pastes the last thing you copied to the clipboard)
ctrl + z (undo the last action you did)
ctrl + y (redo the last thing you undid)
once you're comfortable with that,
ctrl + x (cuts the highlighted text. Once you paste that text elsewhere, it deletes the original. Good if you realize that a certain sentence would work better in a different part of your profile.)
If you're trying to ctrl +c and accidentally ctrl + x, the highlighted text might disappear. Don't panic! ctrl + v it right back where it originally was, then just press the ctrl + c as originally intended. If you are not sure whether you pressed the c or the x because the text didn't disappear but it felt wrong, just press the c again (assuming the text is still highlighted). It doesn't hurt anything to ctrl + c the same thing multiple times.
The other difference between "copy" and "cut", is that you usually can only paste the cut text once. However, some programs and/or operating systems (I'm not actually clear on which one controls the clipboard for text...) have changed this so that you can paste your cut text multiple times, so for those the only difference is that the original text disappears.
NOTE: If you ctrl + c something, then ctrl + c something else, you won't be able to ctrl + v the original thing you copied without going back and redoing the copy. ctrl + v only pastes the very last thing you copied or cut.
