Q:i feel like such a lame kid for asking but i'm totally lost on how to use the keyboard shortcuts can you explain them? :)
Sure! Basically, Tumblr lets you jump directly to the next post on your dash using the J key and jump to the previous post using the K key. Once you jump to a post using J or K, you can use L to like that post.

Missing e adds a few more shortcuts that you can use once you’ve jumped to a post using J or K. Not all of them are available by default (some, like Quick Reblog have to be activated in the Missing e settings):
Ewill open that post for editing (if it is your post)Cwill open the comment/reply box for that post so you can leave a reply (type in your reply and hitTabandReturnto send the reply without using your mouse)Mwill bookmark the post using the Bookmarker feature
If you use the Quick Reblog feature:
Rwill reblog the post without leaving the dashShift+Rwill open the manual reblog pageDwill reblog the post to your draftsQwill reblog the post to your queueTwill open the Quick Reblog menu and put the cursor in the Tags field so you can add/edit tags. Then, hitTabandReturnto reblog without using your mouse
In addition, you can press the X key to activate and deactivate the Safe Dash feature. You don’t need to navigate to posts using J/K to use this keyboard shortcut.
