- The previous version of this list got me quite a few suggestions for

- Why use this: This sometimes cures weird problems.
- Learned from: The Macintosh secret trick list, 16 April, 1992.
- -----------------------------------------------------------------------------
- Effect: Don't load extensions and don't execute startup items.
- How to obtain: Hold SHIFT during startup.
- Restrictions: System 7.
- Why use this: To start a Macintosh with a conflicting collection of

- commendable way to rebuild the desktop...)

- your language.
- In System 6 the files are in MacPaint format, in System 7 in
- PICT format. In System 7 the creator is set to ttxt, but my
- version of TeachText says it cannot display this kind of
- document.

- I know that there is a more recent version of the macintosh secret trick
