Features of CorelDraw or CorelDraw Environment 

Title Bar

The title bar displays the name of the CorelDraw file on which you are working. It is also used to reposition the CorelDraw window on the screen.

Menu Bar

There are 11 pull down menus in the menu bar. All menu commands are found in these pull down menus.

Rulers

Rulers serve as a positioning and sizing aid. They can be turned off optionally. In addition, you can drag guidelines off the rulers to serve as drawing aids.

Scroll Bars

The scroll bars allow you to shift the page horizontally and vertically.

Drawing Windows

The large white portion of the screen is the drawing windows. The rectangle with the drop shadow is the printable page.

Roll-up Window

The Transform (Position) roll-up is shown on the left. Although they are not permanent part of the interface (they can be if you want). You can use them to control many of CorelDraw’s operations. Their beauty lies in the fact that they can remain active for playing quick “what-ifs” without going through the longer process of invoking a standard menu dialog box.

Status Bar

Status bar shows the fill pattern, outline location, movement and absolute coordinates of selected object.

Colour Palette

The colour palette allows for the quick application of a colored fill or outline colour. Selecting the scrollbar at the bottom of the palette opens an expanded color palette.

Page Counter

CorelDraw allows you to create drawings consisting of multiple pages. The total number of pages is displayed in the page counter box along with arrows that allow you to page forward or back in your document.

Standard Toolbar

Toolbar provides quick access to commonly used features. Almost all of these can be accessed through the Menu Bar. CorelDraw provides a series of different toolbars for your use. Additionally, toolbar are completely customizable. You can add buttons to invoke just about any command that you regularly use.

NOTE: There are keyboard shortcuts that are often faster that toolbar usage. Once memorized, you won’t need to waste precious time with a Toolbar button.

Ctrl + S = Save; Ctrl + P=Print; Ctrl + Z=Undo; Ctrl + X = Cut; Ctrl + C =Copy; Ctrl + V= Paste
