|  | # Editing Items
 | ||
|  | 
 | ||
|  | Dynamo-Browse offers some basic facilities for editing items — such as creating items, deleting items, | ||
|  | and modifying their attribute values. | ||
|  | 
 | ||
|  | <figure class="screenshot"> | ||
|  | 	<img src="/images/dynamo-browse/modified-items.png" alt="Item indicators"> | ||
|  | </figure> | ||
|  | 
 | ||
|  | ## Marking Items
 | ||
|  | 
 | ||
|  | Most modifications are applied to items that are marked.  A marked item is indicated by a grey | ||
|  | background and a bullet indicator (`•`) on the left side of the table. | ||
|  | 
 | ||
|  | To mark or unmark the selected item, press <kbd>m</kbd>. | ||
|  | 
 | ||
|  | The command `unmark` can be used to clear all marked items. | ||
|  | 
 | ||
|  | ## Modifying Attributes
 | ||
|  | 
 | ||
|  | Item attributes can be added or modified by using the command `set-attr` or the alias `sa`. | ||
|  | This command can be used to modify the value and type of an attribute of the currently selected items, or | ||
|  | from any marked items. | ||
|  | 
 | ||
|  | The format of the command is as follows: | ||
|  | 
 | ||
|  | ``` | ||
|  | :set-attr [<type>] <attributeName> | ||
|  | ``` | ||
|  | 
 | ||
|  | Where type is one of the following (case insensitive): | ||
|  | 
 | ||
|  | - `-S`: string | ||
|  | - `-N`: number | ||
|  | - `-BOOL`: boolean | ||
|  | - `-NULL`: null | ||
|  | 
 | ||
|  | If the type is not specified, and the attribute exists, then the attribute type will not change. | ||
|  | The type must be specified if this is a new attribute or multiple items have been marked. | ||
|  | After executing the command, Dynamo-Browse will prompt for the value of the new attribute if one is | ||
|  | required. | ||
|  | 
 | ||
|  | Modified attributes will only be tracked in memory: they will not be written | ||
|  | to the actual table until it is "putted" (see [Committing Changes](#committing-changes)). | ||
|  | An item that has been modified will be displayed in red and a modified indicator (`M`) will appear | ||
|  | on the left-most column. | ||
|  | 
 | ||
|  | ## Deleting Attributes
 | ||
|  | 
 | ||
|  | An attribute can be deleted by using the command `del-attr` or the alias `da`.  The format of the command | ||
|  | is as follows: | ||
|  | 
 | ||
|  | ``` | ||
|  | :del-attr <attributeName> | ||
|  | ``` | ||
|  | 
 | ||
|  | When executed, the attribute with the name _attributeName_ will be deleted from the selected item, or | ||
|  | from any marked items. | ||
|  | 
 | ||
|  | Deleted attributes will only be tracked in memory: they will not be removed from | ||
|  | the actual table until it is "putted" (see [Committing Changes](#committing-changes)). | ||
|  | An item that has been modified will be displayed in red and a modified indicator (`M`) will appear | ||
|  | on the left-most column. | ||
|  | 
 | ||
|  | ## Adding Items
 | ||
|  | 
 | ||
|  | A new item can be created by typing in the command `new-item`.   | ||
|  | 
 | ||
|  | When entered, Dynamo-Browse will prompt for the partition and sort key.  Once these are entered, | ||
|  | the item will appear in the top pane in green with an asterisk indicator (`*`) on the left left-most column. | ||
|  | Any additional attributes can be set by using `set-attr`. | ||
|  | 
 | ||
|  | A new item will only appear in memory: it will not be written | ||
|  | to the actual table until it is "putted" (see [Committing Changes](#committing-changes)). | ||
|  | 
 | ||
|  | ## Deleting Items
 | ||
|  | 
 | ||
|  | Items can be deleted by marking them and then typing in the command `delete`. | ||
|  | 
 | ||
|  | Unlike most of the other modified commands, running `delete` WILL make changes to the table | ||
|  | immediately. | ||
|  | 
 | ||
|  | ## Committing Changes
 | ||
|  | 
 | ||
|  | New or modified items (but not deleted items) will be kept in memory until they are committed | ||
|  | or "putted" to the table.  To put the changes, use the `put` command or `w` alias. | ||
|  | 
 | ||
|  | ## Backing Out of Changes
 | ||
|  | 
 | ||
|  | Any modified items can be reverted back to what they are in the actual table by rerunning the | ||
|  | current query.  This can be done by pressing <kbd>⇧R</kbd>.  |
