      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

# vscode-emacs-friendly

This plugin provides emacs keybindings and workflow for Visual Studio Code and is a fork of the great vscode extension by [hiro-sun](https://github.com/hiro-sun/vscode-emacs).

It merges some of the pull requests in the original and other external helpers that make the extension a little less an exact copy of emacs behavior, and a little more friendly in interacting with the system clipboard and normal vscode interactions.

The following are some of the changes and enhancements from the original:

* The clipboard handling is simplified by the removal of the emacs-only kill ring (which was also an unfinished implementation in the original). Copy, Cut, Yank and C-K work with the system clipboard now.
* C+x k to close tab, C+x C-k all tabs
* C+l centers screen on the cursor line
* C+x C+f bound to quick open file
* yank overwrites selection
