Reads the target named under the cursor (or the active selection) and stashes
it via tar_read_stash(), leaving a copy in the global environment as
.target. Bind it to a keyboard shortcut in the RStudio addin manager or a
Positron keybinding, analogous to targets::rstudio_addin_tar_read().
Details
The symbol under the cursor is extracted with
atcursor::get_word_or_selection(), which works in RStudio, VS Code, and
Positron. atcursor is an optional dependency; if it is not installed the
addin prompts to install it from its r-universe repository. If the cursor
is on whitespace with no selection, the addin reports this and does
nothing.
