comment Cheat sheets or reference cards for Mathematica
@Mr.Wizard But it also involves the tedious process of extracting/copying all the shortcuts from the doc page. And it is reasonable to assume that someone has already done that. I really don't want to defend this Q more than necessary, but my main argument is that if there is a useful shortcut sheet, it could be part of the FAQ and should be useful for learners of Mathematica.

max, @Mr.Wizard I've already included the link max just added as the first link. It is now redundant. In my understanding this is a clearcut question: poster requires infor arranged in a one-sheet format.

comment Detecting KeyUp events
@Hector: while your code seems to work, it does not always register the press of the shift key, sometimes misses it (though shift changes, i is not increased).

@Mr.Wizard Please check now. It is far from smooth or robust, but it is a proof of principle.

comment Detecting KeyUp events
@Mr.Wizard I've experimented with this kind of update, with no avail. If you could make it update i in "discrete steps" it would be a useful approach, but this still does not work: old = False; i = 0; Dynamic[If[old =!= shift && shift, i++]; {shift, i}, old = shift; shift := CurrentValue@"ShiftKey"].

CurrentValue["EventKey"] however does not detect all keys, only alphanumeric and punctuation keys, but no Control, Shift, Enter, etc.

comment Syntax formatting when Condition is used with Blank
I guess the reason for the third one is that the syntax highlighter does not check symbols deeper than a certain level to remain fast. For the second one I could only assume that "LocalVariables" in the built-in SyntaxInformation is missing for Condition, while it is added for the operator /; .

comment Is there a “precedence table” for the canonical Sort ordering?
Furthermore, the last point is either confusing or downright wrong: Sort@{"a", "A", "á", "Á"} yields {"a", "á", "A", "Á"}, which seems to imply that Mathematica cannot really distinguish accented characters (as it was already discussed here).

comment Is there a “precedence table” for the canonical Sort ordering?
One consequence of canonical ordering is that e.g. symbols and strings are not sorted intuitively. In canonical ordering the order is {a1, a10, a2, a9} while intuitive sorting gives {a1, a2, a9, a10}. This comes handy when sorting files for example.
