Later, you can quickly come back to that breakpoint by double-clicking +it in the breakpoint list (or select it and click <i>View Code</i>). Since +breakpoints are persistent (i.e. KDbg remembers them across invocations +of a program), you get them back next time you invoke KDbg for that particular +program.</li> + +<li> +You can display a value in the watch section in different ways by prepending +gdb's format specifiers in front of the variable to display.
