'Open in Current Window' and 'Open Reference Image' both use 'Ctrl-Shift-O' in Win 10, but only the latter functions as expected.

Just found your repo recently and I thinks it's by far the best ANSI editor I've ever seen for a desktop and SO MUCH easier to pick up than ACiDDraw, or whatever I used back in the day.

Just wanted to report that the key command, 'Ctrl-Shift-O' is listed as the key command for both of these functions:

• 'File > Open > Open in Current Window'.
• 'View > Open Reference Image...'
  Selecting 'Open in Current Window' from the menu shows me *.ANS and other 'TextArt' files, but the key command does not let you open ANSI files, but instead opens a reference image (which is a really cool feature).

Ideally, I would personally set it up to allow the user to open either type of files and have the software behave differently, depending on what you choose to open (adding a reference image if you pick a PNG, opening a new TextArt editor if you open an ANS file when you already have one open).

I also don't really understand why to specify 'Open in Current Window' just to make it open files like every other program, or why the program creates a new instance every time I open a file, but maybe this is a function specific to creating ANSI art that I don't understand.

And that's a small complaint and something I'll gladly put up with for such a great tool.

Thank for making this!
