Cursors special

Tests shall be performed to check the data entry functions and the proper rejection of out-of-boundaries values. Where applicable, the mouse, graphic digitizer, or pen interface is checked for correct reaction to the user s commands. These tests include cursor movement checks, button verifications (simple- and double-click, left, right, and center, or special functions when applicable), and dragging operations. 

The Help pages available via the corresponding pull-down menu, are organized in a hierarchy with information on different levels. Two ways to exploit Help exist, either by using the Help menu system or by using a special cursor. Starting from a main topic associated subtopics on lower levels may be accessed. 

The display hardware requires a high resolution unit (512 x 512 can be acceptable for some use, others may require 1024 x 1024) capable of at least 16 gray shades or colors (the human eye can distinguish 64 shades of gray). Some form of hardcopy is needed. The most appropriate is a photographic device (Dunn Instruments or Matrix - about 10,000). A "pick" device - a light pen, cursor, or tablet - is sometimes desirable to indicate special regions of interest. 

You may be intrigued to find that this special INPUT routine even works in direct mode. You can still LIST and RUN, but cursor controls remain disabled. Just press RUN/STOP-RESTORE if you want the special INPUT routine out of your way. 

Many of the programs in this book contain special control characters (cursor controls, color keys, reverse video, and so on). To make it easy to know exactly what to type when entering one of these programs into your computer, we have established the following listing conventions. 

Generally, program listings will contain words within braces which spell out any special characters DOWN would mean to press the cursor-down key, and (5 SPACES) would mean to press the space bar five times. 

A special tutorial instructs students in the use of the mouse prior to the onset of SPS instruction about story problems. Students move into the SPS instruction only when they have demonstrated competent use of the mouse. The mouse tutorial takes only about 5 min. It explains to the student how to move the cursor on the screen by moving the mouse, and it gives the student practice in making menu selections and in moving items around on the screen. At the end of the tutorial, the student completes a short exercise using the skills just learned. If the student appears to have trouble manipulating objects on the screen, the tutorial provides additional practice. 

The final processing steps before plotting or the export to the clipboard are the definition of the ID spectra to be used as projections, the choice of the number and relative intensity of the contour levels and the selection of the plot parameters. The main functions of the spectrum window are combined in the upper part of the button panel as shown in Fig. 3.17 and are executed or enabled by a click of the left mouse button. Some functions have their own special cursor mode and it is only possible to leave these functions by clicking the function button again. 

One of the very interesting things about Guide (which goes for some other hypertext systems, too) is that the mouse cursor changes as it passes over areas on the screen with special characteristics. For example Figure 1 shows the initial screen when the student has started the Guide lesson. 

Slip trimming is performed by pressing the Alt key on yonr keyboard while dragging the edge of an event. Watch for the mouse cursor to change from the regnlar Draw or Paint tool cursor to the special slip trim cursor when the Alt key is pressed. 

Volume and Pan envelopes (as well as FX envelopes) are track-level envelopes— that is, they run across an entire track, affecting every event in that track. Individual events can also be quickly faded in or out using event fade envelopes, otherwise known as Attack-Sustain-Release (ASR) envelopes. To create an event fade, move the mouse cursor over the upper (left or right) corner of an event. The cursor changes to the special event fade cursor (see Figure 4.4). Drag the fade envelope in towards the center of the event. 

The mouse cursor changes to a special cursor when positioned correctly. The position of the end of the fade is displayed in a ToolTip (where the gain = 0.0 dB) and the feded portion of the event is visually feded as well. 

Working with Odesolve the user can choose an algorithm for the numerical ODE solution. If the cursor is above Odesolve keyword, the right-click will activate the corresponding context menu (Fig. 3.3). In Mathcad 2001-13 the user could choose between integration with a fixed (Fixed) or adaptive (Adaptive) step as well as a special method for stiff systems integration (Stiff). A new option, Adams/BDF, was added in Mathcad 14-15.
