Configuration System: Input
The Input section gives you control over the two main input devices to your computer, the keyboard and the mouse. Click the Input icon to open this window.
The Keyboard section allows you to modify the way in which the keyboard works. Click the Keyboard icon to open this window.
At the top you can set the country. This can be important because some countries arrange the keys differently or have different keys on the keyboard. For example only a UK keyboard would have a '£' key.
Auto repeat is the time you have to hold down a key before it begins to repeat and then how fast it repeats. If you set the delay to be too short then you may find you ttyyypppeee llllliiiikkkeeee tttthhhiiiissss.
When Enabled is not ticked the keyboard will not auto-repeat.
The Caps Lock section has three options - labelled On, Off and Transpose Cases. If the Caps Lock key on the keyboard is pressed the indicator light in the top right hand corner will come on and when you press the alphabet keys they will appear in upper case. This option sets the Caps Lock key on by default.
Transpose Cases is similar, but some keyboard actions are slightly different. In either case to produce a lower case letter you need to use the Shift key, that is, the action is the opposite of normal for an alphabet key.
The Num Lock enabled option activates the number lock on the numeric keypad. This ensures that you can use it just as you would a calculator. Without the Num Lock key enabled the numeric keypad acts as a series of arrow keys. On a RISC OS keyboard these are not shown as arrows but for those using a non-RISC OS alternative it's possible that arrows are printed alongside the numbers.
Finally, the PC delete option alters the action of the Delete key. Normally both the Delete and Backspace keys will delete the character before the cursor. With PC delete ticked the Delete key will delete the character under the cursor, that is, it deletes forwards as is the usual method for the PC.
The next option allows you to re-configure the mouse.
The top item in this window is Mouse speed. This is the relationship between the distance you move the mouse and the distance the pointer moves on screen. The more you drag the slider to the right the more the pointer will move relative to the mouse.
The next item lets you set the type of mouse. For most users this will be Standard mouse. The other options, which can be selected from the menu, are PS2 mouse and two different types of Serial Mouse. As a word of caution if your mouse works then it is set up correctly, changing the setting, even if you think it is wrong, will probably stop the mouse from working.
Do not select PS2 mouse if you are using a PS2 mouse with an adaptor, these alter the output from a PS2 mouse to make it look like a Standard mouse. This option is for models like the RiscStation, A7000, Omega and Mico which use a PS2 mouse directly. If you are using a PS2 mouse through an STD interface, make sure you select the Standard option from the menu - this will ensure that your mouse runs correctly.
The next two items set the amount of time you have to hold down the mouse button and the distance you have to drag an object before it is interpreted as a drag rather than just being selected.
Double-click delay is the amount of time you have to make the second click when double-clicking on an object. More experienced users may wish to shorten this time from the default of one second to avoid two rapid single clicks being interpreted as a double-click. Double-click cancel distance is the distance you have to move the pointer between clicks for the second click to be interpreted as a new click and not a double click.
Some software, such as drawing or DTP programs, will allow you to drag an object within a window and if you pause at the edge the window scrolls so you can reach the part of the window you wish to drag to. Autoscroll delay is the length of the pause before the window scrolls.
Click to open submenu ensures that submenus will only open if you click on the submenu arrow of a menu item or click with MENU on the item itself.
Menus opened in this way are more persistent than you may be used to because they will not close if you accidentally move the mouse over other parts of the parent menu.
Pointer over submenu arrow opens means that submenus will only open if you actually move the mouse over the small arrow at the side of menu items.
Pointer over arrow or menu item opens makes submenus of a menu open when you move the pointer over that item and close again when you move off it, like the way sub-menus open in Windows. This is not normal RISC OS practice, but you may prefer it. The two items below it only become active if this option is selected, and let you set the delay before the submenu opens when you move onto the menu item and closes again when you move off it.
Bring icon bar forward automatically is extremely useful. If this is ticked then, if the icon bar is covered by a window, when you move the mouse pointer to the bottom of the screen the icon bar will automatically move on top of the window so that you can get access to it without moving the window.
The final option deals with mouse scrolling. Click the Mouse Scroll icon and this window opens:
This window allows you to set RISC OS to respond when a wheel-enabled mouse is plugged into the computer. Wheel mice are increasingly becoming the standard for Windows XP machines; and the Mighty Mouse from Apple provides the same functionality on the Mac OS X platform.
With the Allow scroll wheel to control windows option ticked, RISC OS will respond when you use the scroll button on a mouse.
The Scroll Speed tells the computer how fast windows should scroll in comparison to everything else on the system. We'd recommend leaving this at the default, unless you have any major issue with the speed of response.
Underneath the Scroll menu there are four options.
The latter options operate on a similar basis.
