I export to HTML fairly often with orgmode. In this case “export and open” resulting in viewing the code is almost never what I want; it would be much more useful like the export pdf option, which doesn’t view to the LaTeX code but right to the PDF. Answer As per https://emacs.stackexchange.com/questions/2387/browser-not-opening-when-exporting-html-from-org-mode A setting change fixed this. M-x customize-variable org-file-apps and for files of type \\.x?html?\\' I specified firefox %s. Now it does what I want.

The ability to split emacs windows is highly useful, whether you are using it to view related information in the same window or others. However, after the initial 50-50 split, splitting again will result in 50-25-25, 50-12.5-12.5-12.5-12.5, etc; this becomes unsightly quickly. The solution is the `balance-windows` command, bound by default to C-x++. This equalizes the sizes of all windows, without you needing to reach for the mouse to drag window boundaries.

I was several years into my Emacs usage before mis-types revealed the glory of the “narrow” and “widen” functions to me. Actually, it was one of those nightmares: “Whoa! Where’d my document go!? And why isn’t “undo” bringing it back?” When the tears subsided, I soon realized how useful these commands are. By selecting a region and narrowing it you focus your editing and attention on a portion of what might otherwise be massive files; by so doing, your search/replace commands and your commands to jump to buffer boundaries are contained in a useful area.
