[Qemu-commits] [COMMIT 0ca9f8a] offer right-ctrl as a grab option |
Date: |

From: Dustin Kirkland <address@hidden>
Add support for -ctrl-grab to use the right-ctrl button to grab/release
the mouse in SDL.
The multi-button ctrl-alt and ctrl-alt-shift grab buttons present an
accessibility problem to users who cannot press more than one button
at a time.
