Chapter 9: Completion 48
Once installed, Icicles can be activated by evaluating (maybe place in ‘~/.emacs’):
(require ’icicles)
(icy-mode 1)
Icicles can be toggled at any moment by typing M-x icy.
When Icicles is on, TAB offers completion, provided the conditions determined by ess-
first-tab-never-complete allow it. Typing M-TAB will attempt completion regardless.
Typing M-? in ESS or iESS modes brings up the relevant completion candidates from which
to choose. Minibuffer input filters the available candidates. Use TAB for prefix completion
or S-TAB for substring or regexp completion. Use S-SPC to match an additional pattern
(repeatable). You can cycle among the matching candidates, choosing with RET or mouse-2.
