How should different sized RAM be added to iMac?

Use editres

You cannot save what you configured through XTerm's own menu. BUT, XTerm is a well behaved X application and as such it supports the editres protocol. So what you should do is:

1. Launch XTerm
2. Launch editres
3. Use the 'Get Tree' command of editres to get the Xt widgets tree of the XTerm (you simply click on the XTerm)
4. Select the 'vt100' widget and click on 'Show resource box'
5. Look at the bottom of the resource box, you may have to resize it, and set the 'Save File' filename
6. Click on the wanted resources and set their values
7. When done, click the 'Save file' button and quit editres

The save file can now appended to your .Xdefaults.

Example of what I got by this procedure:

.xterm.vt100.utf8: true
.xterm.vt100.utf8Fonts: true
.xterm.vt100.utf8Title: true
.xterm.vt100.vt100Graphics: true
.xterm.vt100.dynamicColors: true
.xterm.vt100.reverseVideo: true
.xterm.vt100.rightScrollBar: true
.xterm.vt100.scrollBar: true
.xterm.vt100.colorRVMode: true

Beware, some options take effects only when some other option changes. For instance: rightScrollBar is looked up by Xterm only when scrollBar changed from false to true.

But all in all you should have the possibility to do the configuration you want.

Just add all your gear to your favorites, but don't assign any number to them.

This way, you can easily go through your favorites menu and remove the check on everything. When you are done you can toggle everything on again. This should be an easier way than going through the whole item menu system...

After looking around the UI for a bit, I can conclude that there is currently no way of doing this in a straight-forward manner.
