 Writing a number to the write-only 
 .BR leds
-file changes the status leds on the keyboard. The value of the
+file changes the status leds on the keyboard. the value of the
 number is the addition of 1, 2 and 4 representing activated
 Scroll, Num and Caps leds.

-The
-.BR repeat
-file sets typematic rate and delay.  The value of the number is a
-bitmask where first 5 bits set the repeat rate (ranging from 0b00000
-for 30Hz to 0b11111 for 2Hz).  Bits 6 and 7 set the delay before the
-first repeat is activated (ranging from 0b00 for 250Hz to 0b11 for
-1000Hz).
 .SH EXAMPLE 
 Set the Scroll and Caps leds:
