+# normacos
+This keymap was designed especifically to be used on a MacOS High Sierra system with constant use of the Terminal, as it includes a multitude of macros for both the terminal as well as Spotlight Search.
+
+Norman keyboard layout [info page.](https://normanlayout.info/)
+
+Some Norman layout keys were placed on different layers and different positions based on available space.
+
+
+Macros:
+- CtlEsc sends Escape when tapped, and Control when held.
+- SftEnt sends Enter when tapped, and Shift when held.
+- Lock locks the computer
+- Slack opens Slack through Spotlight Search
+- Term opens Terminal through Spotlight Search
+- Spot opens Spotify through Spotlight Search
+- Chrome opesn Chrome through Spotlight Search
+- OutLk opens Microsoft Outlook through Spotlight Search
+- ScnSht allows the user to take a screenshot of a selected portion of the screen
+- ClrHom clears Terminal line from beginning of line up to cursor
+- ClrEnd clears Terminal line from cursor up to end of line
+- ShHome moves Terminal cursor to beginning of line
+- ShEnd moves Terminal cursor to end of line
+- Search activates Terminal Reverse Search Command History
+- Sudo elevates last Terminal command
+- UpDir moves working directory to its parent
+
+Any and all empty keys shown below are will be set in the future, and do nothing as of the time of this writing.
+
+
