What is the easiest way to dump a REGION of memory in IDA pro?

Question

I'm facing a problem that i need to dump a large region of memory with IDA pro

using xdbg its easily done by going to memory map tab and just dumping a region, how can i do this in IDA pro? for example dump from address x to y

I tried to use a simple IDApython script but if the size is large IDA will just crash (I'm dumping a large region while remotely debugging a windows kernel)

filename = AskFile(1, "*.bin", "Output file name")
address = startAddress
size = 0xFFFFFF
dbgr = True
with open(filename, "wb") as out:
    data = GetManyBytes(address, size, use_dbg=dbgr)
    out.write(data)

Without scripting:

1. Select the range:

Go to start of the area, press Alt+L, go to the end

2. Edit, Export data (or Shift+E)

3. pick "raw bytes" and enter filename in the Outpuf File field.

With scripting:

idc.savefile(filename, 0, startAddress, size)
