You can set preferences for general application operations, editing operations, and clipboard operations.
Set General preferences
Document- or Object-level undo
Document-level undo maintains a single list of all your actions for the entire Flash Professional document. Object-level undo maintains separate lists of your actions for each object in your document. Object-level lets you undo an action on one object without having to also undo actions on other objects that might have been modified more recently than the target object.
note: Object-level undo is deprecated with Flash Professional CC.
To set the number of undo or redo levels, enter a value from 2 to 300. Undo levels require memory; the more undo levels you use, the more system memory is consumed. The default is 100.
To open a new document tab in the application window when you select Control > Test, select Open Test Movie In Tabs. The default is to open the test movie in its own window. To have panels in icon mode auto collapse when you click outside them, select Auto-Collapse Icon Panels.
To control how multiple elements are selected, select or deselect Shift Select. When Shift Select is off, clicking additional elements adds them to the current selection. When Shift Select is on, clicking additional elements deselects other elements unless you hold down the Shift key.
Shows tooltips when the pointer pauses over a control. To hide the tooltips, deselect this option.
Selects objects when any part of them is included in the marquee rectangle when dragging with the Selection or Lasso tools. The default is that objects are only selected when the tool’s marquee rectangle completely surrounds the object.
Show axes for 3D
Displays an overlay of the X, Y, and Z axes on all 3D movie clips. This makes them easier to identify on the Stage.
To use span-based selection in the Timeline, rather than the default frame-based selection, select Span Based Selection.
Named Anchor On Scene
Make the first frame of each scene in a document a named anchor. Named anchors let you use the Forward and Back buttons in a browser to jump from scene to scene.
To use the current layer’s outline color, select a color from the panel, or select Use Layer Color.
Printing (Windows only)
To disable PostScript® output when printing to a PostScript printer, select Disable PostScript. By default, this option is deselected. Select this option if you have problems printing to a PostScript printer; however, this option slows down printing.
Auto-Recovery (CS5.5 only)
When enabled (the default setting), this setting saves a copy of each open file at the specified time interval, in the same folder as the originals. If you have not saved the file yet, Flash saves the copies in its Temp folder. The file names are the same as the originals, with “RECOVER_” added to the beginning of the file name. If Flash Pro quits unexpectedly, a dialog box appears when you restart to allow you to open the auto-recover file. When you exit Flash Pro normally, the auto-recover files are deleted.
Scale Content (CS5.5 only)
Options for scaling content when resizing the Stage with the Document Properties dialog box (Modify > Document). To keep objects aligned to the top left corner of the Stage, select Align Top Left. To resize items in locked and hidden layers of the Timeline, select Include Locked and Hidden Layers.
Set AutoFormat preferences for ActionScript
(Windows only) Specifies the maximum color depth of image data copied to the clipboard. Higher depth images are copied at the lower resolution. It is best to set this to the highest depth of the images you plan to work with
(Macintosh only) Specifies the maximum color depth of image data copied to the clipboard. Higher depth images are copied at the lower resolution. It is best to set this to the highest depth of the images you plan to work with
Indicates the resolution to use for image data copied to the clipboard. It is best to set this to the highest resolution of the images you plan to work with.
(Windows only) To specify the amount of RAM that is used when placing a bitmap image on the Clipboard, enter a kilobyte value in the Size Limit text field. Increase this value when working with large or high-resolution bitmap images.
Set text preferences
For Font Mapping Default, select a font to use when substituting missing fonts in documents you open in Flash Professional.
For Vertical Text options, select Default Text Orientation (deselected by default).
To reverse the default text display direction, select Right To Left Text Flow (deselected by default).
To turn off kerning for vertical text, select No Kerning (deselected by default). Turning off kerning is useful to improve spacing for some fonts that use kerning tables.
For Input Method, select the appropriate language.
Set warning preferences
To receive a warning when you try to save documents with content that is specific to the Adobe Flash Professional authoring tool as a Flash CS5/5.5 file, select Warn On Save For Adobe Flash CS4 Compatibility (default).
To receive a warning if the URL for a document changed since the last time you opened and edited it, select Warn On URL Changes In Launch And Edit.
To receive an alert when Flash Professional inserts frames in your document to accommodate audio or video files that you import, select Warn On Inserting Frames When Importing Content.
To receive an alert when selecting Default Encoding that could potentially lead to data loss or character corruption, select Warn On Encoding Conflicts When Exporting ActionScript Files. (For example, if you create a file with English, Japanese, and Korean characters and select Default Encoding on an English system, the Japanese and Korean characters are corrupted.)
To receive a warning when you attempt to edit a symbol with timeline effects applied to it, select Warn On Conversion Of Effect Graphic Objects.
To receive a warning when you create a site in which the local root folder overlaps with another site, select Warn On Sites With Overlapped Root Folder.
To receive a warning when you convert a symbol with a behavior attached to a symbol of a different type—for example, when you convert a movie clip to a button—select Warn On Behavior Symbol Conversion.
To receive a warning when you convert a symbol to a symbol of a different type, select Warn On Symbol Conversion.
To receive a warning when Flash Professional converts a graphic object drawn in Object Drawing mode to a group, select Warn On Automatically Converting From Drawing Object To Group.
To display warnings on controls for features not supported by the Flash Player version that the current FLA file is targeting in its publish settings, select Show Incompatibility Warnings On Feature Controls.
Warn on Document Auto-Save and Auto-Recovery (Flash Pro CS5.5 only). If checked, Flash will remind you to enable Auto-Save for any document that you have saved and then modified if it does not already have Auto-Save enabled. This reminder occurs only once for each document.
Set Publish Cache preferences (CS5.5 only)
The Publish Cache stores fonts and MP3 sounds in order to speed up SWF file creation when you use the Publish or Test Movie commands.
During a Flash session, the first time you create a SWF file from a FLA file, Flash Pro puts compressed copies of any fonts and MP3 sounds you are using into the Publish Cache. During subsequent Test Movie or Publish operations, if the fonts and sounds are unchanged in the FLA, the versions from the cache are used to create the SWF file.
Only MP3 event sounds to which Flash is adding additional compression are added to the Publish Cache. Streaming sounds are not added to the cache.
Memory cache size limit
The maximum amount of RAM to use for the Publish Cache. When the cache exceeds this amount, entries that have not been recently used are moved to disk.
Maximum size for memory cache entry
The maximum size of an individual compressed font or MP3 sound that can be added to the Publish Cache in RAM. Larger items are written to disk.
To clear the Publish Cache, choose Control > Clear Publish Cache or Control > Clear Publish Cache and Test Movie.
