    INSTRUCTIONS:
        1.1) unselect "Show folders" to hide folders
        1.2) select "Show all" to show unreadable files
        1.3) press "<<", "<" or "^^" to select the folder containing the files to be renamed
        1.4) insert a text with wildcards in "Filter" field to show only some files
            eg. "*.jpg" to show jpegs, "a*" to show files starting with "a", "*" to show all
            choose "Invert" to show the files not filtered
        1.5) press "Select all" to select all currently shown files
        1.6) double click on a folder (or link) name to browse it
        1.7) click on a file name to select it, press also <Ctrl> or <Shift> or move mouse to multi-select
        2) to change the name of selected files use the panel on the right.
            Renaming is done with the use of an "imaginary" cursor that is controlled
            by the various gadgets.
        2.1) use "Trim" to remove some characters
        2.2) use "goto", "find" and "skip" to move the cursor (possibly from the tail of the name)
        2.3) use "select to" and "select" to select some characters
            beware the selection always goes from left to right.
        2.4) choose to "cut" or "copy" the selection.
            If you see some characters disappear you know you are "cutting"
        2.5) use "goto", "find" and "skip" to move the cursor (possibly from the tail of the name)
        2.6) select "Paste" to insert selected text into current position
        2.7) use "Insert" to insert additional text into current position
        2.8) select "Insert file's date" to insert the last modified date of the file in one of the
            two formats into current position
        2.9) select "Insert number" to insert auto-numbering into current position
            You can decide the starting number, the increment and a padding text
        2.10) select "Change case to" and choose type to change characters case.
        2.11) press "Reset to defaults" to put all values to their initial state.
        2.12) select "Include extension" to rename also the files suffices
           
        3) press "Execute renaming of selected files" to rename files.
       
        4) press "Undo last renaming operation" to restore previous file names
            warning: you can undo ONLY ONE operation
