Action name: AskNextImmediateThis command searches for the first instruction or data byte that contains the specified immediate value. The command is relatively slow (but much faster than the text search), because it disassembles each instruction to find the operand values.
If the immediate value in an instruction has been logically or bitwise negated, then this command will check against the modified value. Example:
mov al, -2will be found if the user searches for the immediate value 2 but not when he searches for 0xFE.
If the checkbox "any untyped value" is checked, then the "value" field is ignored. IDA will look for all immediate values without type in this case.
