toolbar button, or Ctrl+T hot-key sequence
to toggle between clock time and relative time modes. There are a number of options that let you adjust several characteristics of DebugView, including the way that it behaves and looks.
DebugView displays time stamps of
captured debug output in one of two formats: as clock-time (the time of
day), or as relative time. When displaying relative time DebugView
represents the time of a debug output record as the difference between
its timestamp and the timestamp of the first record in the display. This
mode is helpful when you debug timing-related problems. Use the Options|Clock
Time menu item, toolbar button, or Ctrl+T hot-key sequence
to toggle between clock time and relative time modes.
When DebugView is in clock-time mode you can select the Options|Show Milliseconds menu item to have DebugView show timestamps that include millisecond resolution.
The default behavior of DebugView is to buffer output strings in an internal buffer DebugView maintains until a carriage-return is encountered or the buffer overflows. This allows applications and drivers to build output lines with multiple invocations of debug output functions.
Select Options|Force Carriage Returns to cause DebugView to display every string passed to a debug output function on a separate output line, regardless of whether the string is terminated with a carriage return.
Use the Options|Auto Scroll menu item, 
toolbar
button, or Ctrl+A hot-key sequence to toggle DebugView between
auto-scroll and non-auto scroll modes. When in auto-scroll mode DebugView
will always keep the most recent debug output visible in the display window.
You can gain more display space by hiding the DebugView toolbar. Use the Options|Hide Toolbar menu item or Ctrl+B hot-key sequence to toggle the toolbarÆs presence. DebugView will remember the toolbar state when you exit it and restore the same state the next time you start it.
Setting this option using the Options|Win32 PIDs menu item will cause DebugView to prefix Win32 debug output with either the process ID (Windows NT/2K) or the process name (Windows 9x) of the process that generated the output. Deselecting this option can save screen space if you are not interested in what process generates Win32 output.
Use the Edit|Font menu entry to open a font-selection dialog where you can choose a font that DebugView will use in its output window.
To keep DebugView as the top-most window on the desktop, use the Options|Always On Top menu item. Selecting the menu item a second time will toggle off the always-on-top mode.
