AskNextText

Description

This command searches for the specified substring in the text representation of the disassembly. This command is a slow command, because it disassembles each instruction to get the text representation. IDA will show its progress on the indicator (Options → General → Analysis). You can interrupt this command pressing Ctrl-Break.

You may search for regular expressions too.

If a range is selected using anchor (action Anchor), IDA will search for the specified substring in the range.

Note that this command searches the same as what you see on your screen (and not in binary image).

For binary search, look at AskBinaryText action.
