 Stepping through code ~

 Put focus on the gdb window to type commands there.  Some common ones are:
-- CTRL-C    interrupt the program
-- next      execute the current line and stop at the next line
-- step      execute the current line and stop at the next statement, entering
-	    functions
-- finish    execute until leaving the current function
-- where     show the stack
-- frame N   go to the Nth stack frame
-- continue  continue execution
+- CTRL-C	interrupt the program
+- next		execute the current line and stop at the next line
+- step		execute the current line and stop at the next statement,
+		entering functions
+- finish	execute until leaving the current function
+- where		show the stack
+- frame N	go to the Nth stack frame
+- continue	continue execution
 
-In the window showing the source code some commands can used to control gdb:
- :Break     set a breakpoint at the current line; a sign will be displayed
- :Delete    delete a breakpoint at the current line
- :Step	    execute the gdb "step" command
- :Over      execute the gdb "next" command (:Next is a Vim command)
- :Finish    execute the gdb "finish" command
- :Continue  execute the gdb "continue" command
+In the window showing the source code these commands can used to control gdb:
+ :Run [args]	    run the program with [args] or the previous arguments
+ :Arguments {args}  set arguments for the next :Run
+
+ :Break		set a breakpoint at the current line; a sign will be displayed
+ :Delete	delete a breakpoint at the current line
+
+ :Step		execute the gdb "step" command
+ :Over 		execute the gdb "next" command (:Next is a Vim command)
+ :Finish	execute the gdb "finish" command
+ :Continue	execute the gdb "continue" command
+ :Stop		interrupt the program
 
 The plugin adds a window toolbar with these entries:
-  Step	    :Step
-  Next	    :Over
-  Finish    :Finish
-  Cont	    :Continue
-  Eval	    :Evaluate
+  Step		:Step
+  Next		:Over
+  Finish	:Finish
+  Cont		:Continue
+  Stop		:Stop
+  Eval		:Evaluate
 This way you can use the mouse to perform the most common commands.
