Create your pattern inside the pattern workspace instead, then you can see it tile as you work. Start with a square or rectangle, create the pattern from that shape, delete the shape, then draw your organic shapes.
Another possibility is to right click the text layer, and convert it to a Smart Object. This avoids the need to rasterize the text.
Then you can apply a Blending mode to the Smart Object Layer.
If you need to edit the text, double click the Smart Object in the Layers panel. It will open the Smart object for editing, then finally and close the Smart Object.
This was not asked, but inserting a blending mode to the colored text will not make it look like it's painted on the wall. More plausible result can be got with 3 additional tricks:
Perfect clean edges should be distorted to match the apparent roughness of the wall material.
The paint layer must also have some apparent depth. It either ...
You can set a blending mode for the Gradient Overlay...
If the desire is to have the Gradient Overlay be the only color of the type, you'll want to set the Fill Opacity of the Type Layer to 0 (zero) in the Blending Options for the layer or via the Layers Panel.
Fill Opacity effects only the actual pixels on a layer... where as Opacity effects the pixels on ...
This is an example using Illustrator CC, but as far as I remember it was the same in earlier versions.
You can click and drag tabs off the tab bar, and manually reposition and resize the document windows.
Not really sure what you're trying to do, but if you're editing some text with the Type tool T, you first need to hit Esc to stop editing with the Type tool, before hitting V for Move tool.
Or just use your mouse and click the Type/Move icons in the main toolbar.
You can group panels so they will open as tabs when one of them is clicked.
When you drag and drop those panel icons you can either drag them onto another panel to add them to the same group or you can create a separate panel by dragging it at the bottom of the bar (or between two icons).
You must go into Pattern Editing mode to edit patterns. Pattern creation typically causes, and demands, the breaking of any links when the tile is initially created.
Patterns can not contain linked content. Even things such as internal document links, i.e. symbols, will be broken for pattern tiles.
First, if the desire is multiple windows tiled on screen, you can not use tabbed documents. At least not in CS6.
Tabs won't allow the creation of tillable windows, you can't tile tabs. So you first must navigate to Illustrator > Preferences > User Interface and uncheck Open Documents as Tabs. Or merely create floating windows of what you want tiled (In ...
The order of things is imperative.
With the Free Transform Tool active...
Click a handle.
Then hold the modifier(s) down.
All this must be done in that 1-2-3 order specifically. At a minimum you must click before pressing the modifiers.
For free distort, hold the Command/Ctrl key
For symmetrical distort, hold Command/Ctrl+Option/...
