 &lt;p&gt;Easy mode. Implied for &lt;code&gt;evim&lt;&#x2F;code&gt; and &lt;code&gt;eview&lt;&#x2F;code&gt;. Starts with &lt;code&gt;&#x27;insertmode&#x27;&lt;&#x2F;code&gt; set and behaves like a click-and-type editor. This sources the script $VIMRUNTIME&#x2F;evim.vim. Mappings are set up to work like most click-and-type editors, see &lt;code&gt;evim-keys&lt;&#x2F;code&gt;. The GUI is started when available.&lt;&#x2F;p&gt;
