+# FOCUS SETTING ATOM
+
+## Description
+
+With this patch, dwm monitors the content of the `_DWM_FOCUS` property in the
+root window (a 32-bit cardinal) and sets the focus accordingly, selecting the
+client tags and monitor if needed.
+
+## Usage
+
+After patching, you can use a modified verwion of lsw to print the window id:
+
+ diff -up lsw-0.1/lsw.c lsw.new/lsw.c
+ --- lsw-0.1/lsw.c 2006-10-13 11:09:18.000000000 +0200
+ +++ lsw.new/lsw.c 2010-02-23 15:15:41.468637549 +0100
+ _AT_@ -63,7 +63,7 @@ main(int argc, char *argv[]) {
+ continue;
+ getname(wins[i]);
+ if(buf[0])
+ - fprintf(stdout, "%s\n", buf);
+ + fprintf(stdout, "%s - %i\n", buf, wins[i]);
+ }
+ }
+ if(wins)
+
+And then call dmenu to choose a window by title, xprop to set it:
+
+ win="$(lsw | grep -v ^\<unknown\> | dmenu | awk '{print $NF}')"
+ test $win && xprop -root -f _DWM_FOCUS 32c -set _DWM_FOCUS $win
