The original vim's redo command (Ctrl+Shift+R) doesn't work

[SebasSBM]

Describe the bug
The original vim commandline editor permitted to undo with u, and redo with Ctrl Shift R. This plugin is unable to redo with Ctrl Shift R.

To Reproduce
Steps to reproduce the behavior:

1. Empty file
2. i, type "This sentence will be undone..."
3. u to undo
4. Ctrl Shift R to redo
5. Didn't work, VSCode Menu --> Edit --> Redo
6. Didn't work either

Expected behavior
Pressing the keys Ctrl Shift R should work to redo (the original Vim worked that way)... it would also be prefereable that the u and Ctrl Shift R original undo/redo functions (respectively) were integrated with Vs Code's undo/redo functionality.

Environment (please complete the following information):

• Extension (VsCodeVim) version: 1.2.0
• VSCode version: 1.32.3
• OS: Linux Mint 17.2 Rafaela

Isn't it Ctrl r (no shift)?

I wasn't aware of it either, but seems like ctrl+shift+r works also

@rickythefox, you are right! For some reason, I had it memorized as ctrl+shift+R... but, even in original Vim, it also works with ctrl+r...

I also tested it in VSCodeVim, and it works as expected...

I'm sorry for opening an issue due to such a mistake of mine...
