问题 I generally use Python 2.7 but recently installed Python 3.5 using Miniconda on Mac OS X. Different libraries have been installed for these two versions of python. Now, the entering either of the keywords 'python' or 'python3' in terminal invokes python 3.5, and 'python2' returns '-bash: python2: command not found'.

问题 I've been googling around trying to figure out if it's possible to use my mouse wheel to scroll while inside Vim in Mac's Terminal, with no luck. It seems as if only X11 or iTerm support this.
