How do I navigate buffers in astrovim?

Question

I switch between tabs with <leader>bb and typing in the letter that appears on the tab. Is there a faster way? For example, it will switch to a tab to the right / left.

Answer 1

Yes, faster than your example and default Astronvim way is
[b - go to previous buffer
]b - go to next buffer.

Answer 2

Set keyboard shortcuts to Tab and Shift+Tab

vim.api.nvim_set_keymap('n', '<S-Tab>', ':bprev<CR>', { noremap = true })
vim.api.nvim_set_keymap('n', '<Tab>', ':bnext<CR>', { noremap = true })
