I want that XEmacs window to be -sticky, without having to use the window manager's function to set the -window sticky. What gives? - - `xemacs -name' sets the application name for the program (that is, -the thing which normally comes from `argv[0]'). Using `-name' is the -same as making a copy of the executable with that new name. The -`WM_CLASS' property on each frame is set to the frame-name, and the -application-class. So, if you did `xemacs -name FOO' and then created -a frame named BAR, you'd get an X window with WM_CLASS = `( "BAR", -"Emacs")'. However, the resource hierarchy for this widget would be: - - Name: FOO .shell .container .BAR - Class: Emacs .TopLevelEmacsShell.EmacsManager.EmacsFrame - - instead of the default - - Name: xemacs.shell .container .emacs - Class: Emacs .TopLevelEmacsShell.EmacsManager.EmacsFrame - - It is arguable that the first element of WM_CLASS should be set to -the application-name instead of the frame-name, but I think that's less -flexible, since it does not give you the ability to have multiple frames -with different WM_CLASS properties. Another possibility would be for -the default frame name to come from the application name instead of -simply being `emacs'. However, at this point, making that change would -be troublesome: it would mean that many users would have to make yet -another change to their resource files (since the default frame name -would suddenly change from `emacs' to `xemacs', or whatever the -executable happened to be named), so we'd rather avoid it. - - To make a frame with a particular name use: - - (make-frame '((name .

TeX mode defines the key `"' to +insert ```' after whitespace or an open brace, `"' after a backslash, +or `''' otherwise. This is done by the command `tex-insert-quote'. If +you need the character `"' itself in unusual contexts, use `C-q' to +insert it. Also, `"' with a numeric argument always inserts that +number of `"' characters. + + In TeX mode, `$' has a special syntax code which attempts to +understand the way TeX math mode delimiters match. When you insert a +`$' that is meant to exit math mode, the position of the matching `$' +that entered math mode is displayed for a second. This is the same +feature that displays the open brace that matches a close brace that is +inserted.

When given at the end of a +line, `C-t' transposes the last two characters on the line, rather than +transposing the last character of the line with the newline, which +would be useless. If you catch a transposition error right away, you +can fix it with just `C-t'. If you catch the error later, move the +cursor back to between the two transposed characters.

Otherwise, a +reverse search (`C-r') is often the best way. *Note Search::. + + `Meta-t' (`transpose-words') transposes the word before point with +the word after point.

For example, `C-u 3 C-t' moves the character before +point forward across three other characters. This is equivalent to +repeating `C-t' three times. `C-u - 4 M-t' moves the word before point +backward across four words. `C-u - C-M-t' would cancel the effect of +plain `C-M-t'. + + A numeric argument of zero transposes the character (word, sexp, +line) ending after point with the one ending after the mark (otherwise a +command with a repeat count of zero would do nothing). + + +File: xemacs.info, Node: Fixing Case, Next: Spelling, Prev: Transpose, Up: Fixit + +Case Conversion +=============== + +`M-- M-l' + Convert last word to lower case.
