Action name: HideThis command allows you to hide a part of disassembly. You can hide a function, a segment, or create a special hidden range.
If a range is specified, a special hidden range is created on this range.
If the cursor is on the segment name at the start of the segment, the segment will be hidden. IDA will display only the header of the hidden segment.
If the cursor is on a structure variable and if the target assembler has the 'can display terse structures or the INFFL_ALLASM' bit on, then the structure will be collapsed into one line and displayed in the terse form.
Otherwise, the current function will be hidden. IDA will display only the header of the hidden function.
If there is no current function then IDA will beep.
If you want to see hidden items on the screen, you may use unhide command or enable the display of the hidden items. If you want to delete a previously created hidden range, you may use del hidden range command.
