Use SlickEdit commands instead of the mouse to save time as you work. Open the SlickEdit command line by pressing Esc (in most emulations), type the command and any options, then press Enter. If you use a command frequently, bind it to a keyboard shortcut to save even more time. Type “Slickedit command line” in the Help Index (Help > Index) to learn more.

This is to make it possible to create a multi-line comment without temporarily commenting out all the code from the /* to the end of the file or to the end of  the next already existing multi-line comment.  This makes it possible to keep your file in a syntacticly correct state.  This allows you to use things like tag navigation or statement navigation to move to the location where you want to end the comment.  When you type */ in order to close the comment, the editor will search backwards for a matching /**/ and patch things up by deleting the */ characters.  The unique thing about this technique is that it gives you the benefit of keeping your code syntactically correct without actually changing what you type to create a comment at all.  You still type /*, then move your cursor down, then type */, just like you did before.

SlickEdit supports RTF and HTML clipboard formats for Windows. This means you can paste formatted and color-coded text from SlickEdit into other applications. The HTML clipboard format type is enabled by default. You can change to the RTF format or turn the feature off completely using the Clipboard formats option (located at Tools > Options > Editing > Selections).
