$ elogv

Inside the program, you can use these keys:

• Down arrow -> Scroll the list of files down by 1 unit
• Up arrow -> Opposite of Down arrow
• Page Down -> Scroll the list down by 10 units
• Page Up -> Opposite of Page Down
• End -> Go to the last file of the list
• Home -> Go to the first file of the list
• t -> Order the list of files by date, most recent on top
• a -> Order the list of files alphabetically
• r -> Reverse the list of files
• SpaceBar -> Scroll the selected file
• h or F1 -> Show the help screen, press Page Up/Down to scroll up and down, h and F1 again to hide
• d -> Remove log files, usage is similar to vim "d" command, here are same examples: da -> Remove all files de -> Remove from selected item to the end of the list ds -> Remove from selected item to the start of the list d1d or dd -> Remove selected file only d4d -> Remove 4 files starting from selected one
• q -> Quit
