Clicker 1.0: A key-click commodity REQUIREMENTS An Amiga running at least release 2.0 of the OS (KickStart V36 or better), a keyboard, and a loudspeaker to hear the sounds through. COPYRIGHT This program is in the Public Domain. That means you can legally create and publish an improved version and claim full copyright over it; in fact I would probably help you do so in any way I can. Even claiming copyright over my unmodified work would technically be legal, but you would make yourself look like a complete arse if you did. In fact I would probably help you do so in any way I can. I'm serious. Take a look at the sources, they're quite clean and readable if you are familiar with C. It's pure ANSI C and not (too) dependent on any particular compiler. INTRODUCTION This program makes a clicking noise each time you press a key. Call me crazy (I mean really, go ahead, everybody's doing it) but I hate to use keyboards that don't click. Why? Well first of all I find no encouragement in a machine which just doesn't seem to care. The Amiga is a caring and personal system and it should give you some kind of happy feedback --just to show you that it's listening. Second I like to type without having to look intently at the screen all the time. Whether it's because somebody is talking to me and I have to pretend to listen patiently while I'm really still programming, or just because the A4000 keyboard doesn't have a reassuring clonk to it so you have to press the keys all the way down to make sure that it got the message. Clicker lets me type lighter and faster because one gets to know exactly how much pressure the keys require. Oh and third of course, it annoys the hell out of everybody in a five-meter radius so they have something to talk about and can stop worrying about their own problems for a minute (it's an odd thing really that so few people at university appreciate what I'm doing for them). Try it! INSTALLATION This is the simple part. Just drag the program icon anywhere you like. If you want Clicker to be started automatically when you boot your computer, drag it into the WBStartup drawer on your system disk. USAGE Double-clicking the Clicker icon or typing its name from the shell will start the program. Once Clicker is running, double-clicking the icon or typing the name again will bring up the program's preferences window. This is still very primitive (no loading or saving yet), but at least it lets you alter volume, pitch and duration of the clicks. The window can also be brought up by selecting Clicker's entry from the program list in the Commodities Exchange window and clicking on the Show Interface button. You can also disactivate and reactivate Clicker from there, or quit the program altogether. Here's an overview of the controls in the preferences window: * Click Mouse Button: If you want Clicker to make its key-click noise for mouse-button presses as well as when keys are pressed, select the "Click Mouse button" gadget. * Pitch: You can pick any tone from the musical scale for the key-click noise. The frequency in Hertz is shown next to the Pitch slider; Drag the slider to the left to get a lower tone, or to the right to get a higher one. Unfortunately there's only a very short range of useful pitches at the moment. (For the musically literate user: In a vain and deluded attempt to not offend anybody's ears the tone of the clicks can be selected over a 9-octave range of the equal-temperament tuning based on the 440-Hertz A) * Length: This determines how long the noise of every click should last. Because the duration of a key click is typically very short, the Length setting does not regulate the number of microseconds the sound is played, but the number of times the entire wave-form sample is played altogether. This means that with the same Length setting you will get longer duration for low pitches than with higher pitches. OPTIONS Shell command-line template: PITCH/N VOLUME/N LENGTH/N CLICKMOUSE/S Icon tooltypes: PITCH= VOLUME= LENGTH= CLICKMOUSE= See USAGE for an explanation of these settings.
