Version 0.04

- Changed name from 'osm' to 'vdr' to avoid mixups with the 'oms' program that
  appears to be in use with DVD replay.
- Implemented a channel display in the top menu line.
- Implemented replay progress display (press "Ok" when replaying to bring it up).
- Implemented direct channel selecting by pressing the numeric keys.
- Added several 'const' keywords to please stricter compilers.
- The repeat function for the remote control no longer adapts dynamically
  to the timing of the RCU (this sometimes caused the repeat function to
  kick in too early).
- Channel selection is now blocked when recording or replaying.
- Improved process handling.

 ---------------------------------
 
+* Navigating through the On Screen Menus
+
+  The "Main" menu can be called up with the "Menu" key of your remote
+  control unit. The "Up" and "Down" keys are used to select a specific
+  item. The "Left" and "Right" keys can be used to change options, and
+  the numeric keys allow direct input of numeric data. The "Ok" key
+  confirms any changes (or switches to a channel in the "Channels" menu).
+  The "Back" key goes back one level in the menu structure, discarding
+  any changes that might have been made in the current menu.
+  
+  In the "Timers" menu, the current timer can be enabled or disabled with
+  the "Right" or "Left" key, respectively (enabled timers are marked with ">").
+  "Ok" here opens the "Edit timer" menu.
+  
+  Textual options, like channel names or recording file names, can be edited
+  by pressing the "Right" button (which puts brackets around the current
+  character as in "[R]TL"), selecting the desired character position with
+  "Left" and "Right", and changing the character with the "Up" and "Down"
+  keys. "Ok" then confirms the changes.
+  
+  The "Red", "Green", "Yellow" and "Blue" buttons have special meanings
+  in the various menus and are listed at the bottom of the on-screen-display.
+  
+  At any point in the menu system, pressing the "Menu" key again will
+  immediately leave the menu system.

 * Selecting a Channel
 
-  You can select a channel either by pressing the "Up" or "Down" key (while
-  no On Screen Menu is displayed), or browsing through the channel list in
-  the menu and pressing "Ok" on the desired channel.
+  There are three ways to select a channel:
+
+  1. With no On Screen Menu displayed press the "Up" or "Down" key to switch
+     to the next higher or lower channel.
+  2. Press the "Menu" button to bring up the On Screen Menu, select "Channels"
+     and browse through the list with the "Up" and "Down" key; to switch to the
+     selected channel press "Ok".
+  2. Directly type in the channel number with the numeric keys ('0'..'9');
+     if no key is pressed for about half a second, the digits collected so
+     far will define the channel number.
+
+  After switching to a different channel the channel number and name, as well
+  as the current time are displayed at the top of the screen. This line
+  automatically goes away after about two seconds, or if any key is pressed.
+  To bring up the channel display without switching channels you can press
+  the "Ok" button.
 
 * Instant Recording
 
   You can start recording the current channel by pressing the "Record"
-  button. This will create a timer event named "instant" that start
+  button. This will create a timer event named "instant" that starts
   at the current time and records for two hours.
   If you want to modify the recording time you need to edit the timer.
   Stop instant recording by disabling or deleting the timer.
