The really nerdy/geeky nerds use a Dvořák layout or a chorded keyboard…
Why not just discard e? I hardly put it in anything that I do.
As someone involved with communications concerning navigation, this.
Are you perchance related to Ernest Vincent Wright?
No! If you’re a heavy MS Word user, you’re going to need the ^ for text searches.
How do you post here? I use square brackets for bold, italics, quote, etc. Is there another way?
Or did I just admit that I am being [wooshed] ?
For italics, use an asterisk before and after the word(s). For bold, use 2 asterisks. For bold italics, use 3 asterisks. Also, there’s a menu at the top of the reply box with all this, plus quote and link.
I’d like a ⎕ (quad).
This is the correct answer. It can replace the caret.
Send caps lock into orbit, somewhere it won’t cause trouble. Replace it with another modifier key (like shift or alt or ctrl), so it doesn’t matter if it’s hit accidentally. Call in over for overstrike. Use it to permit accents or carrots over any previous character. Also question marks over explanation points and explanation points over question marks. In combination with other keys it could turn on or off bolding, italics or -wait for it- capitalization. But you would need to hold down 2 (3?) keys simultaneously for that, and listen to the 1812 overture.
ETA: Or maybe switch the caps lock with one of the Alt keys, and replacing the 2nd Alt key with an overstrike key.
Nothing comes to mind that hasn’t already been mentioned but, looking at the suggestions, I feel like the ° would probably be the most generally useful.
I think é is the character I most often copy/paste from into various documents.
° or º ? The first one is Option-Shift-8 on a Mac; the second is Option-0.
Not the “degree” symbol 
My dirty dirty secret is, sometimes I copy and paste from the character picker.
I just keep a printed copy of this table of Windows codes handy, for the occasions when I need one.
Reminds me of this little dustup in the Linux community recently.
Basically, there is a difference between the ASCII Hyphen-Minus and the Unicode Hyphen. They’re rendered identically, or close to it, but coded differently. One of the tools they use to generate man (help) pages changed the handling so that they used hyphens by default.
Unfortunately, most OSes are configured so that the dash button produces a Hyphen-Minus. So if you searched for, say “--help” in the page, it wouldn’t find it, despite the text clearly being there. It’s just that your search text had a Hyphen-Minus and what you were looking for contained a Hyphen.
It was a mistake to ever give typographers access to computers. They’ve caused an incredible amount of damage over the years. Unicode itself is basically unforgivable.
I needed an umlaut on my typewriter so I just filed off the bottom of the “X”. My friends said I was crazy, but I told them you can’t make an umlaut without breaking an X.
° not º, I primarily write English and occasionally Afrikaans, I have no need for that particular ordinal indicator. I find myself using ° a lot, though. For both temperatures and angles.
And that’s nice, that you have options (heh), but neither exists on my Dell.
Hear, hear.
Bravö.
Yes, I get the degree symbol and the ordinal indicator confused, but so what – they look practically the same! 
Yes! Genius.
