Hi,

There are a number of the program's features that could benefit from keyboard shortcuts to help make navigation around the product even more efficient. My pick for top candidates:
- Ctrl + O to open a new file, plus add Alt or Shift modifiers to allow opening the other log types
- Ctrl + W or Ctrl + F4 for closing the current log file
- Ctrl + Tab and Ctrl + Shift + Tab for moving right and left (respectively) through the open logs
- Clearing the current log (Ctrl + X is used in DebugView)
- Auto-scroll to bottom
- Opening the Highlight menu from the toolbar
- Always on top
- Ctrl + F to filter (its close enough to find that the misuse of this common keyboard shortcut would be acceptable)
- Ctrl + C to copy the currently selected lines from the active log
There may be others you want to add but these are the ones I'd expect to be used frequently enough to warrant the effort.

The majority of these shortcuts will be very familiar to any Windows user and will help make the program more intuitive especially for power users. And less face it, if you are using this program you are likely to be a power user and have a tendency to use keyboard shortcuts.

Thanks,
Matt
