4.5 Escape ‘$’

Suppose that you want to put the ‘*’ marks to messages matched to a pattern specified to the ‘/’ command. If there are messages marked with ‘*’ already, these messages are merged to the results of ‘/’. Thus, you would want to escape the current messages marked with ‘*’.

For this sake, the escape mark ‘$’ is provided. A typical usage is as follows:

1. Change the ‘*’ marks to the ‘$’ marks with ‘m$’.
2. Put the ‘*’ marks to messages, for instance, with ‘/’ and process the messages marked with ‘*’.
3. Cancel the ‘*’ marks with ‘U*’.
4. Get the old ‘*’ marks back with ‘m*’.

Here is summary of the commands related to the ‘$’ mark.

‘m$’

Change the ‘*’ marks to the ‘$’ marks.

‘m*’

Change the ‘$’ marks to the ‘*’ marks.
