Typically C-Backspace and C-Delete

I am use to the Emacs binding of C-K

Instead of escape showing the "Execute MPSL" dialog, have it be an entry that allows various fancy Vim operations. For example, entering: 5dd would delete 5 lines while 8yy would copy 8 lines. s/John Doe/Jane Smith/ would replace John Doe with Jane Smith, etc...

Say your cursor is marked by @

print("Hello@World");

If you were to expand the selection, it would look back to find the first one of '"([{ and then select from the beginning character to the matching '")]} character. So, If _ represented the selection, after expanding the selection once it would you would have:

print("_Hello@World_");

Now, expanding again would find the (...) so the selection would be:

print(_"Hello@World"_);

etc...

Given the lines and the cursor being marked by @:

ttk::text $win.grid1.size2 -row 0 -column 1
ttk::text $win.grid1.size3 -row 0 -column 2
@```

If the Duplicate Same function were executed, it would duplicate on the third line everything that is the same between the two previous lines, thus you would wind up with:

ttk::text $win.grid1.size2 -row 0 -column 1
ttk::text $win.grid1.size3 -row 0 -column 2
ttk::text $win.grid1.size@```

The Duplicate Same function could run many times on that line. It should execute from the current cursor position forward until the first difference between the two previous lines.
