As noted in the code, the stack has the following issues: - Modifiers are not reported correctly (ctrl pressed reports as ctrl+alt) - Doing buffer switches in the action results in the new buffer recieving button up and setting a selection. - Scintilla docs says indicator release event gets modifiers - we do not.
Items are loaded whenever pagedown or down is pressed while at the last line. The loading is no longer naive, but just appends the items which makes for instant loading. The max_shown_items settings is removed since it no longer serves a purpose.
