 ## Blocks
 Every individual Component is contained in its own block. These can be added, removed, moved and resized. Each block has its own header which can be right clicked to reveal more operations you can do with that block.

-### Preview
-Preview is the generic type of block used for viewing files. This can take many different forms based on the type of file being viewed.
-You can use \`wsh view [path]\` from any Wave terminal window to open a preview block with the contents of the specified path (e.g. \`wsh view .\` or \`wsh view ~/myimage.jpg\`).
-
-#### Directory
-When looking at a directory, preview will show a file viewer much like MacOS' *Finder* application or Windows' *File Explorer* application. This variant is slightly more geared toward software development with the focus on seeing what is shown by the \`ls -alh\` command.
-
-##### View a New File
-The simplest way to view a new file is to double click its row in the file viewer. Alternatively, while the block is focused, you can use the ↑ and ↓ arrow keys to select a row and press enter to preview the associated file.
-
-##### View the Parent Directory
-In the directory view, this is as simple as opening the \`..\` file as if it were a regular file. This can be done with the method above.  You can also use the keyboard shortcut \`Cmd + ArrowUp\`.
-
-##### Navigate Back and Forward
-When looking at a file, you can navigate back by clicking the back button in the block header or the keyboard shortcut \`Cmd + ArrowLeft\`.  You can always navigate back and forward using \`Cmd + ArrowLeft\` and \`Cmd + ArrowRight\`.
-
-##### Filter the List of Files
-While the block is focused, you can filter by filename by typing a substring of the filename you're working for. To clear the filter, you can click the ✕ on the filter dropdown or press esc.
-
-##### Sort by a File Column
-To sort a file by a specific column, click on the header for that column. If you click the header again, it will reverse the sort order.
-
-##### Hide and Show Hidden Files
-At the right of the block header, there is an 👁️ button. Clicking this button hides and shows hidden files.
-
-##### Refresh the Directory
-At the right of the block header, there is a refresh button. Clicking this button refreshes the directory contents.
-
-##### Navigate to Common Directories
-At the left of the block header, there is a file icon. Clicking and holding on this icon opens a menu where you can select a common folder to navigate to. The available options are *Home*, *Desktop*, *Downloads*, and *Root*.
-
-##### Open a New Terminal in the Current Directory
-If you right click the header of the block (alternatively, click the gear icon), one of the menu items listed is **Open Terminal in New Block**. This will create a new terminal block at your current directory.
-
-##### Open a New Terminal in a Child Directory
-If you want to open a terminal for a child directory instead, you can right click on that file's row to get the **Open Terminal in New Block** option. Clicking this will open a terminal at that directory. Note that this option is only available for children that are directories.
-
-##### Open a New Preview for a Child
-To open a new Preview Block for a Child, you can right click on that file's row and select the **Open Preview in New Block** option.
-
-#### Markdown
-Opening a markdown file will bring up a view of the rendered markdown. These files cannot be edited in the preview at this time.
-
-#### Images/Media
-Opening a picture will bring up the image of that picture. Opening a video will bring up a player that lets you watch the video.
