Here is the old section from the tutorial. Removed it as helm/ivy is a choice that will depend on customization.
HELM
Helm is a very useful package. Boon provides special support for it.
>> If you have not done it yet, install helm now: (package-install ‘helm)
The command ‘\[helm-occur]’ starts `helm-occur’; which does a quick search for all occurrences of a pattern in the current buffer.
>> Type ‘\[helm-occur]’ now
>> Within the helm prompt area, type ‘helm <return>’ to jump to the beginning of this section.
You can search for the current symbol by typing SPC in an empty helm mini-buffer.
>> Move the cursor to an occurrence of the helm word, and type ‘\[helm-occur] SPC’.
\<boon-helm-command-map> >> Use C-\[helm-previous-line] and C-\[helm-next-line] to select an occurrence, then type <return> to jump to the currently selected occurrence
Note: after typing \<helm-map>\[helm-previous-line], it suffices to type \<helm-map>\[helm-previous-line] to perform `helm-previous-line’. The keys which do not require repeating the C- prefix are: \{boon-helm-command-map} \<boon-command-map>
Besides `helm-occur’, a few other helm commands are bound to keys starting with the same prefix:
\[helm-apropos] –> `helm-apropos’ \[helm-resume] –> `helm-resume’ \[helm-show-kill-ring] –> `helm-show-kill-ring’
The full list of key bound to that prefix is: \{boon-goto-map}
I tried to do this following the code in Evil but it does not work.
According to Sefan Monnier (private email), creating a buffer without setting up the “fundamental mode” is not allowed. So there is nothing to do except bug the maintainers of the offending packages.
