any space that I press while shift is depressed is void. However, having installed Yosemite, it no longer works in GUI MacVim, rendering this: I will have my shift pressed exactly twice (for and, respectively). Up until now, all versions of Vim (including MacVim) that I ever ran would render Shift-Space in insert mode as equivalent to Space. Another issue on Yosemite while it may be trivial, it is really annoying, and I wonder if anyone has insight.
