   - **Print var:** Automated insertion of print statement to print a variable
     at a given point in the code. This map can be made with either visual or
     normal mode:
-    - Using this function in normal mode will automatically find the variable
-      under the cursor and print it.
     - Using this function in visual mode will print out whatever is in the

   - **Cleanup:** Automated cleanup of all print statements generated by the
