+### Control scheme
+
+The control scheme is vim-like and features a minimal line editor as well as datetime-input.
+
+- `j`/`k`: move focus down/up
+- `J`/`K`: move focused entry down/up
+- `<space>`: toggle focused entry completed
+- `q`: save and quit
+- `Q`: quit without saving
+- `g`/`G`: move focus to top/bottom
+- `s`: cycle sort mode. 
+
+
+### TODO
+
+Things that might be implemented in the future
+
+- more controls
+    - `a`/`A`: append to entry text (enters line editor)
+    - `c`/`C`: change entry text (enters line editor)
+    - `i`/`I`: insert before entry text (enters line editor)
+    - `o`/`O`: edit new entry (after/before current - enters line then datetime editor)
+    - `r`: replace entry
+    - `/`/`?`: search entry by text (backwards) (wrapping)
+        - later on regex search
+    - `u`/`<ctrl-z>`: undo
+    - `<ctrl-r>`/`<ctrl-y>`: redo
+    - `z`: collapse/expand current group
+    - `yd`: copy entry date
+    - `yt`: copy entry text
+    - `yy`: copy entire entry
+    - `0`-`9`: as prefix for repeated commands
+
+- line editor with vim commands (prefixed with mode)
+    - normal: `<esc>`: exit line editor
+    - normal: `a`/`A`: append (to end)
+    - normal: `i`/`I`: insert (at beginning)
+    - normal: `d`: delete
+    - normal: `x`: remove character
+    - normal: `c`/`C`: change
+    - normal: `r`/`R`: replace
+    - normal: `s`/`S`: substitute (equal to `cl` and `cc` respectively)
+    - normal: `v`: visual mode
+    - normal: `y`/`Y`: copy
+    - normal: `p`/`P`: paste
+    - normal: `u`/`<ctrl-z>`: undo
+    - normal: `<ctrl-r>`/`<ctrl-y>`: redo
+    - normal: `f`/`F` and `t`/`T`: find (until) (backwards)
+    - normal: `/`/`?`: search (backwards) (wrapping to beginning of line)
+        - later on regex search
+    - insert: `w`,`b`,`e`: like vim, including uppercase equivalent
+    - insert: `<esc>`: exit line editor
+    - insert: `<ctrl-w>`/`<ctrl-backspace>`: delete last word
+    - insert: `<ctrl-shift-v>`/`<shift-insert>`: paste
+    - visual: `a`/`i`: select all/inside of...
+
+- datetime editor
+    - highlight date part (YYYY for example)
+    - `d`: remove entire deadline
+    - `<enter>`: go to next part
+    - `0`-`9`: input number (ignoring invalid inputs like months >12)
+
+- sort mode: cycle through modes and set ascending/descending separately
+    - `r`: insert before entry text (enters line editor)
+
+- collapsable todo group hierarchy
+    - detect indent width from md
+    - group entries together under previous entry with lower indent level
+    - display expandable groups in tui
+
+- config
+    - keybinds
+    - some other options (?)
+
+- some `:`-commands?
+    - regex substitution
+    - set commands for config entries
+    - help command that shows controls
+    - `set` with no key shows explicitly set keys (config and live)
+    - config wizard & write current config state to config file
