 ### Added
 - Adds rich tooltip details to most nodes in the **GitLens** explorer and **GitLens Results** view
 - Adds an indicator to the *GitLens* explorer branch history to mark the synchronization point between the local and remote branch (if available)
+- Adds a one-time notification on startup if the `alternate` set of keyboard shortcuts is in use, with options to easily switch to another set
 - Adds `${agoOrDate}` and `${authorAgoOrDate}` tokens to `gitlens.blame.format`, `gitlens.currentLine.format`, `gitlens.explorers.commitFormat`, `gitlens.explorers.stashFormat`, and `gitlens.statusBar.format` settings which will honor the `gitlens.defaultDateStyle` setting — closes [#312](https://github.com/eamodio/vscode-gitlens/issues/312)
 - Adds `gitlens.currentLine.scrollable` setting to specify whether the current line blame annotation can be scrolled into view when it is outside the viewport — closes [#149](https://github.com/eamodio/vscode-gitlens/issues/149), [#290](https://github.com/eamodio/vscode-gitlens/issues/290), [#265](https://github.com/eamodio/vscode-gitlens/issues/265)
 - Adds *Copy Commit ID to Clipboard* (`gitlens.copyShaToClipboard`) command to changed file nodes in the **GitLens** explorer and **GitLens Results** view
