- Become a Power-User part 3
-
- We conclude this look at some of the features of RISC OS which
- make life easier by examining new features introduced in RISC
- OS 3. Some of these require the support of the application
- concerned to work.
-
- * Dragging one or more objects between two directory viewers
- copies them to the directory. If you hold down the SHIFT key the
- objects will be moved rather than copied. On RISC OS 3 objects
- will be renamed rather than copied if possible.
-
- * Help (ie from !Help) is now available on menu entries.
-
- * Clicking on the Toggle Size icon with SHIFT held down will open
- a window to it’s largest possible size without obscuring the icon
- bar.
-
- * If you drag a scroll bar with the Adjust button and the window
- has both vertical and horizontal scroll bars the pointer will
- temporarily disappear, and the mouse can be used to scroll the
- window in both directions while you hold ADJUST down.
-
- * If you click Select within a directory viewer in a position which
- is between objects, you can then drag a rectangle around all the
- objects which you wish to perform an operation on. Individual objects
- can be added or removed from the group by clicking Adjust on them.
-
- * Clicking on the close icon of a window with SHIFT held down does
- not close the window, but instead ‘iconises’ it on to the Pinboard
- (the Backdrop program). Double-clicking on the iconised window
- restores it to full size.
-
- * While a window is iconised, you can get at the relevant menu for
- that window by using SHIFT-Menu with the pointer over the iconised
- window.
-
- * SHIFT F12 brings the icon bar to the front of the desktop (beware
- applications which also use it!). It can also put it back at the back.
-
- * CTRL F12 starts a Task Window.
-
- Some questions and myths about viruses
-
- Now that viruses are becoming more common on RISC OS machines, there
- are a number of common questions which crop up.
-
- * Should I inoculate my files ?
-
- Do not use any inoculation program. It is not possible to
- simultaneously inoculate against all the known viruses.
-
- * I've got the version n.nn of !xxxxxxx, and that doesn't find anything.
- So I'm protected, right ?
-
- Wrong. The virus scene changes very rapidly. If the program you are
- using is more than 3-6 months old, it will not detect the newect viruses
- and newly discovered strains of existing ones (at the time of writing 23
- families of virus exist). Futhermore, using an out-of-date program has
- the possibility of spreading a virus through your system as it scans,
- and of corrupting data when attempting to disinfect a file (because the
- infection is of a different strain, discovered more recently).
-
- * Can a virus reside in the CMOS RAM ?
-
- No. The CMOS RAM is only used for data storage. Program code is never
- executed within the CMOS RAM. In addition, it is only 240 bytes long.
- However, some viruses do use CMOS RAM locations for data storage.
-
- * Can a virus survive a CTRL-Reset ?
-
- No. However, it will probably not take long to reload it - see below!
-
- * How can I be infected with a virus ?
-
- Opening a directory viewer on a directory containing an infected
- application is enough - you don't have to actually use an application
- which is infected.
