32.6.5.5 Other Buffers
Input/Output Buffer
If the variable gdb-use-inferior-io-buffer is non-nil, the executable program that is being debugged takes its input and displays its output here, otherwise it uses the GUD buffer. To toggle the use of this buffer, do M-x gdb-use-inferior-io-buffer.

Some of the commands from shell mode are available here. See Shell Mode.

Locals Buffer
The locals buffer displays the values of local variables of the current frame for simple data types (see Frame Info).

Arrays and structures display their type only. With GDB 6.4 or later, move point to their name and press <RET>, or alternatively click Mouse-2 there, to examine their values. With earlier versions of GDB, move point to their type description ([struct/union] or [array]). See Watch Expressions.

Registers Buffer
The registers buffer displays the values held by the registers (see Registers). Press <RET> or click Mouse-2 on a register if you want to change its value. With GDB 6.4 or later, recently changed register values display with font-lock-warning-face. With earlier versions of GDB, you can press <SPC> to toggle the display of floating point registers (toggle-gdb-all-registers).
Assembler Buffer
The assembler buffer displays the current frame as machine code. An overlay arrow points to the current instruction and you can set and remove breakpoints as with the source buffer. Breakpoint icons also appear in the fringe or margin.
Threads Buffer
The threads buffer displays a summary of all threads currently in your program (see Threads). Move point to any thread in the list and press <RET> to select it (gdb-threads-select) and display the associated source in the source buffer. Alternatively, click Mouse-2 on a thread to select it. If the locals buffer is displayed then its contents update to display the variables that are local to the new thread.
Memory Buffer
The memory buffer allows the user to examine sections of program memory (see Memory). Click Mouse-1 on the appropriate part of the header line to change the starting address or number of data items that the buffer displays. Click Mouse-3 on the header line to select the display format or unit size for these data items.
