comment Does $x>0$ imply that $x\in\mathbb{R}$?
The documentation for Simplify states "Quantities that appear algebraically in inequalities are always assumed to be real."

comment shortcut key for traverse command history in a Mathematica session in a terminal?
Does the front end have a way to scroll through command history? I know about Ctrl+L, but that's not the same as the up key in the command-line.

@IstvánZachar How so? I'm curious -- could you explain what you mean a bit more?

...or don't use subscripts. They're used for typesetting, but they're not idiomatic in Mathematica programming.

comment Opening a context menu (with the Menu key)
The problem with this is that a right-click is simulated at the position of the mouse pointer, not on whatever is selected in the Mathematica front end.

comment How to copy hyperlink addresses using the keyboard
@celtschk I don't think so. The right-click code knows what was right-clicked, but I'm not sure how the keyboard-shortcut code would.

comment How to copy hyperlink addresses using the keyboard
It's possible, if one has no other option, to Show Expression (Ctrl+Shift+e) and copy the address from there.

comment How to copy hyperlink addresses using the keyboard
Well, there's more than way of inserting a hyperlink into some text. For example, one can create a hyperlink with Hyperlink and then copy and paste it into the text, or one can select some text and create a hyperlink using the menu. In those two cases, Ctrl+c, Ctrl+v either copies a large TagBox expression or just the text of the hyperlink, not the address (URI). I now see that one possible solution might be to copy the TagBox expression and then use another program to replace the clipboard contents with the hyperlink address, which is inside the expression.

Something like 'a FrontEndToken corresponding to the "Right Click" / "Contxt" ' menu would be crucial.

comment Are there any cases when For[] loops are reasonable?
Perhaps if the algorithm you're implementing lends itself very well to loops your code will be most readable if you use loops.
