The Hazeltine 1500 had a similar feature, invoked using ~, DC1 and then the X and Y positions separated with a comma. One example is the VT52 terminal, which allowed the cursor to be placed at an x,y location on the screen by sending the ESC character, a Y character, and then two characters representing numerical values equal to the x,y location plus 32 (thus starting at the ASCII space character and avoiding the control characters). They are used in development, scientific, commercial text-based applications as well as bulletin board systems to offer standardized functionality.Īlthough hardware text terminals have become increasingly rare in the 21st century, the relevance of the ANSI standard persists because a great majority of terminal emulators and command consoles interpret at least a portion of the ANSI standard.Īlmost all manufacturers of video terminals added vendor-specific escape sequences to perform operations such as placing the cursor at arbitrary positions on the screen. The terminal interprets these sequences as commands, rather than text to display verbatim.ĪNSI sequences were introduced in the 1970s to replace vendor-specific sequences and became widespread in the computer equipment market by the early 1980s. Certain sequences of bytes, most starting with an ASCII escape character and a bracket character, are embedded into text. To find a misplaced pointer by pressing the Ctrl key, under Visibility, select the Show location of pointer when I press the Ctrl key check box.ANSI escape sequences are a standard for in-band signaling to control cursor location, color, font styling, and other options on video text terminals and terminal emulators. To ensure that the pointer doesn't block your view of the text you're typing, under Visibility, select the Hide pointer while typing check box. To make the pointer easier to find when you move it, under Visibility, select the Display pointer trails check box, and then move the slider toward Short or Long to decrease or increase the length of the pointer trail.
In some programs, you'll need to move the mouse pointer to the button you want to click.) To speed up the process of selecting a choice when a dialog box appears, under Snap To, select the Automatically move pointer to the default button in a dialog box check box.
To make the pointer work more accurately when you're moving the mouse slowly, under Motion, select the Enhance pointer precision check box. To change the speed at which the mouse pointer moves, under Motion, move the Select a pointer speed slider toward Slow or Fast. In the search box, type mouse, and then click Mouse.Ĭlick the Pointer Options tab, and then do any of the following:
Open Mouse Properties by clicking the Start button, and then clicking Control Panel.
