** Tips
|
|||
|
|
|
|||
|
|
*** Matching and completion-styles
|
|||
|
|
|
|||
|
|
In addition of multi matching like in all other helm commands, helm-org obey `completion-styles'
|
|||
|
|
which allow having flex aka fuzzy matching, see [[Completion-styles][Completion-styles]].
|
|||
|
|
|
|||
|
|
*** Refiling
|
|||
|
|
|
|||
|
|
You can refile one or more headings at a time.
|
|||
|
|
|
|||
|
|
To refile one heading, move the point to the entry you want to refile and run
|
|||
|
|
\\[helm-org-in-buffer-headings]. Then select the heading you want to refile to
|
|||
|
|
and press \\<helm-org-headings-map>\\[helm-org-run-refile-heading-to] or select the refile action from the actions menu.
|
|||
|
|
|
|||
|
|
To refile multiple headings, run \\[helm-org-in-buffer-headings] and mark the
|
|||
|
|
headings you want to refile. Then select the heading you want to refile to
|
|||
|
|
\(without marking it) and press \\<helm-org-headings-map>\\[helm-org-run-refile-heading-to] or select the refile action from the
|
|||
|
|
actions menu.
|
|||
|
|
|
|||
|
|
*** Tags completion
|
|||
|
|
|
|||
|
|
Tags completion use `completing-read-multiple', perhaps have a
|
|||
|
|
look at its docstring.
|
|||
|
|
|
|||
|
|
**** Single tag
|
|||
|
|
|
|||
|
|
From an org heading hit C-c C-c which provide a
|
|||
|
|
\"Tags\" prompt, then hit TAB and RET if you want to enter an
|
|||
|
|
existing tag or write a new tag in prompt. At this point you end
|
|||
|
|
up with an entry in your prompt, if you enter RET, the entry is
|
|||
|
|
added as tag in your org header.
|
|||
|
|
|
|||
|
|
**** Multiple tags
|
|||
|
|
|
|||
|
|
If you want to add more tag to your org header, add a separator[1] after
|
|||
|
|
your tag and write a new tag or hit TAB to find another existing
|
|||
|
|
tag, and so on until you have all the tags you want
|
|||
|
|
e.g \"foo,bar,baz\" then press RET to finally add the tags to your
|
|||
|
|
org header.
|
|||
|
|
Note: [1] A separator can be a comma, a colon i.e. [,:] or a space.

|||
