comment Why are some option values symbols, other strings?
@flip I haven't noticed that, but it's great news. Can you give an example?

comment ArrayPlot: colours depend on image size?
I cannot reproduce the problem either with 10.2.0 OS X or 10.2.0 Linux (Ubuntu 15.04 in a VirtualBox).

comment Replacing the Slot in an expression
Root does work even if the first argument is not a real function though. This works: N@Root[13 - #1^4 + #1^5, 1] (note there's no &!). And even this works: N@Root[13 - x^4 + x^5, 1]. These forms are undocumented and probably a bad idea, but I've seen them used a few times on online forums like this one. Maybe this has contributed to the confusion.

comment LineLegend behaves differently in ListPlot in Mathematica Version10.0 or later
@Harry I have 10.0.2 installed and the date of December 4, 2014 (in $Version) matches with yours. If yours showed an earlier date, I couldn't tell if it was 10.0.0 or 10.0.1 as I don't have those versions any more.

@Harry You're right, see update.

To check version, use Help -> About in the GUI or use both $Version and $ReleaseNumber. Unfortunately $Version and $VersionNumber will not contain the z part of an x.y.z form version number.

comment Mixing Text and Formulas
And this is a 2 yr old question. I didn't realize that.

comment Mixing Text and Formulas
This works for me: Alt+7, This is some text Ctrl-9 x RightArrow. On my keyboard layout Ctrl-9 creates an inline cell where I can type traditional form formulae. Pressing the right arrow key on the keyboard exists this inline cell. On non-English keyboard layouts the shortcut might be different. Go to Insert -> Typesetting and check what keyboard shortcut is listed next to "Start Inline Cell", or just use the menu item.

comment Suppress Print[ ]s?
@JosephO'Rourke Block[{sym}, expr] evaluates expr with the definition of sym temporarily removed. This works even if sym is a builtin like Print. Block[{Print}, ...] makes Print behave like any undefined symbol while the body of the Block is evaluated.

I think I first saw this style used by Brett Champion.

comment I have a problem in plotting simple Exponential Equation?
The syntax you used is not correct. t^-1 cannot be used as a variable in Plot, only simple symbols can. Try ParametricPlot[{t^-1, G}, {t, ...}] or replace t by 1/x in G (ReplaceAll).

comment I want to draw my data on desktop by mathematica
I do not understand the question at all. Please clarify it a bit, e.g. "this is what I did", "this is what I wanted to happen", "this is what happened instead". Give an example.

comment Is there a better way to get nice looking equations in output?
I don't fully understand the question. Are you simply looking to avoid typing TraditionalForm? Any cell can be converted to traditional form using Command-Shift-T, which is quicker.

comment How can I prevent SHIFT-ENTER moving the editing cursor?
If this question is about the programming cloud, please mention is specifically within the body of the post. Do not rely on tags to convey information (at least not in Mma.SE)

I wouldn't delete it, it's still a valid answer for the desktop FE.

comment How can I prevent SHIFT-ENTER moving the editing cursor?
+1 but based on the tags the OP seems to want to do this in the Programming Cloud, where it doesn't work.

There's at least one regular on this site using M 10.2 on Windows 10.

Would you like to comment/answer here, to give those of us who haven't upgraded yet some peace of mind?

comment How to disqualify a rule
This format is very useful for substituting variables. E.g. solve, sol = Solve[equation, x], verify, equation /. sol. Or put the result into a new equation without having to set explicit values to symbols. Ref: reference.wolfram.com/language/tutorial/…

comment How to disqualify a rule
You can add those inequalities to the system of equations you are solving, and switch to Reduce, e.g. Solve[x < 10 && a x^2 + b x + c == 0, x, Reals]. Please use backticks to delimite bits of code in comments.
