In MS Word the users have the ability to embed different objects and files in the document, using the Insert tab -> Text section -> Object. Implement similar behavior in RadRichTextBox, allowing to embed objects as inlines, to edit them, and to re-embed them after editing.

When a preceding paragraph's size is increased, for example - font size is changed, or paragraph is split to two, then the selection of the consequent paragraphs is wrong. When the cursor is on the second line and attempt to select some part of it with the mouse is made, the first or the third line is selected.

Steps to reproduce: 
1. Create two paragraphs with multiple lines
2. Insert new paragraph after the first paragraph
3. Try to select second line of the third paragraph with the mouse

Observed result: First line is selected instead of second line being selected

The background-color attribute could be used for setting a background.

Add support for DeletePreviousWord and DeleteNextWord commands, triggered with Ctrl+Backspace and Ctrl+Delete keyboard shortcuts.

Floating table are tables that can be absolutely positioned in the document, with different text wrapping (similar to floating images). MS Word converts a table to floating object whenever the table is dragged.

Add options in Table Properties dialog similar to MS Word – Table with Text Wrapping: Around and None.

Add support for optional (a.k.a. soft) hyphens. In MS Word, such are inserted using Ctrl + -. If the word need to be split as there is no enough space on the line, the word is split after the optional hyphen.

Support (programmatic and non-programmatic) for Word-like real-time text correction and formatting (similar to AutoCorrect and AutoFormat).

Create UI for editing CITATION fields, a.k.a. "citation placeholder", which later you can edit. 

Currently PdfFormatProvider does not use the track-changes styles when exporting the document. So the different text color, underline, strike through or borders will not appear in the exported PDF.

Consider raising an event when the images are finished loading, or an option for loading the images synchronously. 

DeleteTableRowCommand and DeleteTableColumnCommand should be able to delete all selected table rows/columns at once. Currently, the command cannot be executed when there is selection and  the user should delete the rows/columns one by one.

Implement IF and ASK fields.

This field retrieves a character through a code value specified in the field-argument. Such documents are common and are created when symbols (e.g. with font Windings through Insert -> Symbol dialog) are inserted in RTF documents in MS Word. 
This functionality is also used when content containing <sym> element is copied from DOCX and pasted in RadRichTextBox - as the content is converted to RTF containing SYMBOL field during the operation.

Workarounds: 
- Implement such field with the API, see the documentation article (http://docs.telerik.com/devtools/wpf/controls/radrichtextbox/features/fields-and-document-variables/custom-fields ) and the SDK example (https://github.com/telerik/xaml-sdk/tree/master/RichTextBox/CustomField/ ). Note that MS Word doesn't show field menus for these fields in RTF documents.
- If RTF format is used and you have control over document creation, save the documents initially as docx, and then save them to RTF. This way the symbols will be encoded without the SYMBOL field construct, and are successfully imported in RadRichTextBox.

Available in R3 2018 Official Release.

Currently text in table cell can be oriented only left to right, with horizontal lines flowing from top to bottom. Add support for more text directions - the most common are vertically oriented, i.e. rotated to 90 or 270 degrees.

Provide mechanism for selecting an uri from which a dictionary can be downloaded when needed. In this way the client will download only the dictionaries that are in use. If more are needed, they will be downloaded on demand.

When inserting text (document fragment) next to a correctly spelled word they get both underlined as incorrect.

DocxFormatProvider should support external content (altChunk (Anchor for Imported External Content)) when importing documents. The current version omits anything referred as external content. 

Note: exporting from Telerik Reporting to DOCX when the report contains HtmlTextBox will create such elements.

Copy formatting from one place in the document and apply it to another.

Available in R2 2018 Official Release version.

In some languages such as German and Swedish, combining correct words into one is a common morphological pattern. Compound words not included in the dictionaries should not be marked as misspelled.

When track changes are enabled deleted content is also taken into account when spellchecking.

Steps to reproduce:
- Type in a wrong word (e.g. thos). 

- Turn Track Changes on. 

- Select the o and replace it with i. 

Expected: The word is not considered wrong and underlined by the spellchecker.

Actual:  "thois" is spell checked and evaluated as wrong.
