From the vim-rspec Readme there is this:
map <Leader>t :call RunCurrentSpecFile()<CR>
map <Leader>s :call RunNearestSpec()<CR>
map <Leader>l :call RunLastSpec()<CR>
map <Leader>a :call RunAllSpecs()<CR>
Assuming I am using the default setup (not customizing the keymappings, how would I run one of the above commands within vim? (I’m not sure what Leader means, specifically)
