for Windows 2.0 (1994) Interface Prior to WordStar, word processors split text entry and formatting into separate functions; the latter was often not done until a document was about to be printed. WordStar was one of the first WYSIWYG word processors, showing accurate line breaks and page breaks. It was a major breakthrough to be able to see (and, while writing, force, if one so desired) where line breaks and page breaks would fall — even though, being a text-based program, WordStar couldn't accurately display different typefaces such as bold and italic until version 5.0. In a default installation on a 25-line screen, the top third of the screen contained a menu of commands and a status line; the lower two-thirds of the screen displayed the text of the user's document. A user-configurable option to set the help level released this space for user text. The help system could be configured to display help a short time after the first key of a command sequence was entered. As users became more familiar with the command sequences, the help system could be set to provide less and less assistance until finally all on-screen menus and status information was turned off. The original computer terminals and microcomputers for which WordStar was developed, many running the CP/M operating system, did not have function keys or cursor control keys (arrow keys, Page Up/Page Down). WordStar used sequences of alphabetic keys combined with the "Control" key, which on keyboards of the time was conveniently next to the letter A in the position now usually occupied by the Caps Lock key. For touch typists, in addition, reaching the function and cursor keys generally requires them to take their fingers off the "home keys" with consequent loss of typing rhythm. For example, the "diamond" of Ctrl-S/E/D/X (s=left, e=up, d=right, x=down) moved the cursors one character or line to the left, up, right, or down. Ctrl-A/F (to the outside of the "diamond") moved the cursor a full word left/right, and Ctrl-R/C (just "past" the Ctrl keys for up and down) scrolled a full page up/down. Prefacing these keystrokes with Ctrl-Q generally expanded their action, moving the cursor to the end/beginning of the line, end/beginning of the document, etc. Ctrl-G would delete the character under the cursor. Ctrl-H would backspace and delete. Commands to enable bold or italics, printing, blocking text to copy or delete, saving or retrieving files
