Look in the Menu bar of your computer for Shortcuts - in OS 7.6 it is in the Apple Guide on the right side of the Menu bar. In OS 8.x, it is over towards the left under Help. You will find all the above shortcuts plus many dealing with window, icons, and various miscellaneous topics.
Another good source of information is Extensions Overload. This little item is shareware but well worth the price.
In OS 8.5 and higher, the dotted vertical line next to the finder icon near the right edge of the Menu bar, can be adjusted to show only the active icon or the icon and the name of the active application. You may also drag the finder box to some more convenient location.
OS 9 has occasional problems. The solution to an inaccessible folder is Package First Aid. An uncompressed version is found in the Utilities folder of your OS 9 CD - it may not be readily apparent and it does not load when you install OS 9. The StuffIt compressed version is: OS9Fix
Alias option trick When you are in an Open/Save dialog looking at a list of files, if you hold down the Option key while double-clicking an Alias in the list, you will be transferred to the folder that holds that item. It does not open the file or folder. Note: An Alias is italicized in a list so you can recognize it as one. Also, in attempt to look like Windows, Apple has added a little arrow to the alias icon.
PRAM
Pronounced "Pee-ram," not "pram" is short
for parameter RAM, a portion of memory that stores some basic
but important information that your Mac uses. It can get corrupt,
then you need to ZAP it. That can be done by holding down the
Option, Command and P and R keys while rebooting the computer.
Let it flash on and off 3 or 4 times, then let go of the keys
to continue booting up. A freeware utility called TechTool will
also Zap your PRAM with less hassle. The thing you need to realize
after zapping the PRAM is that some of your settings will go back
to the original defaults; date and time, volume setting, modem
and printer port settings, virtual memory, and so on. You might
even have to go to Page Setup and open, then close it to get something
to print after having zapped the PRAM. It isn't something that
most people have to do often, but when nothing else helps, it
doesn't hurt to try it.
Disk Cache
You find it in the Memory Control panel and it is pronounced "cash",
not "catch" or "cashey" is memory set aside
to provide faster retrieval than if the computer always has to
access the hard disk. Things that make it faster to have a larger
cache set aside are things that you use over and over where you
are asking for the same instructions in one program or if you
are retrieving data from a CD-ROM, since its contents are static.
If you are running several applications at the same time and switch
around from one to another frequently, having a large cache doesn't
help you. Prior to System 7.5, the guide-line was to set your
cache giving 32k for every meg of RAM you have. If you have a
later system, then you can give more cache because it has been
improved to run more smoothly.
