By default the Keyword Complete, Header Parameters, and Function Bookmark functions are accessed through the Popup Tools (2nd button from the right). You may configure the toolbar to access one or more of these directly from toolbar buttons. A future version of SrcEdit may enable you to change icons and the position they display in the toolbar. Until then the user who wants to rearrange or add new icons should edit the resources for SrcEdit.prc using RsrcEdit.
