Search and replace Greek letters in notebook

I often use Greek lett开发者_JAVA百科ers in my calculations. Is there any way, to replace all occurrences of say ø with µ? From a computational/mathematical standpoint, it makes no difference what the variable name is. But sometimes, we are conditioned to use certain variables and become used to them. So if I happen to use an odd variable and need to share my notebook with a colleague, I'd like to change the variable before sending it. Is there an efficient way to search and replace Greek letters in mma?

Using Mathematica 7 or later, you can use the "Find" dialog to do this. Type \[Phi] as the search string and \[Mu] as the replacement string. This may also work in Mathematica 6 or earlier, but I don't have those versions at hand at the moment to try it.

See the "Listing of Named Characters" in the Mathematica help for the escape codes that you can use.

The find and replace dialog should work for this.

Assuming version 8, you can either use long names (\[OSlash]) to input the names, or shortcuts (shift-esc o / shift-esc).

(shift-esc being necessary because plain old esc in the find dialog will dismiss the dialog.)

In earlier versions the long name method should work. (The long name won't collapse into the character, but after finding/replacing it's all fine.)

In mma7, one possibility that is sometimes handy is Use Selection for Find. That is, select the greek letter (or whatever you want to replace), then (from the EDIT menu) -> Find -> Use Selection for Find.

When the Search/Replace dialog box is now invoked, the \ [phi] (for example) will be in the Find dialog box. On a Macintosh, the shortcut is command E (followed by command F). Also works for\ [CapitalDelta] etc.
