Here are several miscellaneous tips:

•  The watch cursor will spin during any time-consuming, interruptible operations.  Use command-period to interrupt the operation.
•  To edit the text in a SimpleText read-only (ttro) document, simply select and copy the text into a new document.
•  Open any file by dragging it onto Tex-Edit Plus.
•  To move a styled Tex-Edit Plus document into another word processor without losing style information, use the clipboard to copy and paste the entire document.
•  Triple click to select a line.
•  Quadruple click to select a paragraph.
•  Option-click on a close box to close all windows.
•  To delete all occurrences of a string, use the Find/Replace dialog.  Just leave the replace field blank and choose Replace All.
•  Count the number of occurrences of any given string using the Find/Replace dialog.  Enter an appropriate number of wildcard characters in the Replace with box, then choose Replace All and note the number of replacements.
•  To see non-printing characters (tabs, CRs, etc.), use the included ASCII fonts.
•  Tex-Edit’s PICT handling abilities are handy when it comes to cropping screen shots (Command-shift-3) for use in other programs (e.g., Word).  Just click-and-drag a selection marquee and choose Copy.
•  If you run out of memory during a PICT copy operation, try keeping the entire selection marquee visible.
•  If you notice a delay when opening or resizing large documents, make sure the text is left justified and Use real tabs is off.
•  A document can be read in the background if Auto-Highlighting is off.  You may use all of Tex-Edit’s normal editing functions during the reading session.
•  To “nest” quoted text (make a quote of a quote), use the Block Options dialog to increase the line length a little before issuing the Block Quote command the second time.
•  To avoid misaligned columns and indents in printouts, leave “Font Substitution” off (in the Page Setup dialog) or use real tabs instead of spaces.
•  All numeric dialog fields have up/down arrow buttons that allow quick adjustment between allowable field values.
